Welcome to Nashville for the 2016 National Pavement Preservation Conference! This event has been designed to provide an extensive presentation of the latest practices and developments in the pavement preservation field. It also provides an excellent forum to establish new contacts within the pavement preservation community and strengthen existing ones. The opening plenary session features remarks from two highly respected keynote speakers who will provide their unique perspective and insight on preservation: Jean-François Corté, past Secretary General of the World Road Association (PIARC), and Carlos Braceras, Executive Director of the Utah Department of Transportation and Secretary-Treasurer of the American Association of State Highway & Transportation Officials (AASHTO). The opening plenary session also includes remarks from Mark McConnell, Executive Deputy Director of the Mississippi Department of Transportation and Chair of the AASHTO Transportation System Preservation Technical Services Program (TSP·2), on TSP·2 program efforts to advance pavement preservation. The Tuesday afternoon agency plenary session includes presentations from Walter (Butch) Waidelich, Executive Director of the Federal Highway Administration, and Brian Stacy, President of the National Association of County Engineers, on the importance of pavement preservation in an agency maintenance program. Concurrent presentation sessions are scheduled throughout the conference along four technical tracks. Each of the tracks offer an opportunity to hear from experts in the pavement preservation field on topics of national importance. Live demonstrations are also scheduled where industry representatives will apply preservation treatments and showcase pavement repair techniques. On Tuesday and Friday mornings, the four regional Pavement Preservation Partnerships will meet to conduct technical presentations, discuss issues of regional importance, and provide state-by-state reporting of preservation activities. We invite you to attend one of these partnership meetings to learn about the practices of member agencies and to participate in the discussion. Throughout the conference, we encourage you to interact with speakers and exhibitors in order to enhance your experience. In addition, the AASHTO TSP·2 program can assist those who have questions or need support in advancing pavement preservation. The program was formed to provide resources that support the adoption of preservation treatments, disseminate information about emerging technologies and best practices, and foster information exchange between agencies, contractors, suppliers, manufacturers, consultants, and academics. In a society where the traditional maintenance philosophy of “worst-first” is often emphasized, we hope that the information presented at this conference inspires you to champion and promote the use of pavement preservation treatments in your workplace and in your community so that we collectively can be “Continuing the Drive for Change.” Sincerely,

National Center for Pavement Preservation Michigan State University

speaker abstracts Adams, Teresa Pavement Preservation for the Anthropocene The term Anthropocene is used to title this presentation as a reminder that transportation and other human activities have a significant impact on the environment at the scale of the entire planet. The risks and trends expressed in USDOT’s “Beyond Traffic 2045: Reimagining Transportation” will be a starting point for multidisciplinary discussions on practices that move beyond making transportation environmentally friendly to balancing the impacts of the transportation system and services on the Triple Bottom Line regionally, nationally, and globally—now and in the future. The presenter will identify strategies to encourage a culture of sustainability in roadway design, construction, operations and maintenance. The goal is to advance concepts of sustainable transportation toward delivering transportation in a sustainable future.

Barnhart, Tracy Making the Most of Your Quality Management System Most of us are familiar with the focus on quality in the construction materials world, but is your company’s quality management system (QMS) really working for you? Learn how your organization can benefit from implementing and continually improving its QMS, starting with an emphasis on what quality is and how it relates to your business. The three main components of a QMS will be explained, with the use of real-world examples. Tips and tricks to maintaining an effective QMS will be discussed, along with pitfalls to avoid. Learn how AASHTO re:source has benefited from developing its own QMS, as well as ways to measure quality. The corrective action process and root cause analysis will also be discussed. A fully documented and effective QMS will ensure that the requirements of both your organization and your customers are met.

Beckemeyer, Curt Integrating the Rolling Wheel Deflectometer (RWD) into Pavement Management to Support an Effective Pavement Preservation Program Pavement structural response is an indicator of pavement structural capacity, which is an important consideration when evaluating pavement preservation strategies. Because of the challenges of collecting structural data on a network level, agencies traditionally have relied on indices derived solely from surface distress and ride

quality, leaving structural condition considerations out of the decision-making process. The Rolling Wheel Deflectometer (RWD) is an innovative device that measures pavement structural response under an 18-kip single axle load traveling at highway speeds. The result is high productivity in data collection and no impacts on traffic. As such, the RWD allows agencies to integrate pavement structural condition into the pavement management process and incorporate decision-making processes that support pavement preservation. This presentation highlights a study performed in collaboration with the Oklahoma DOT to demonstrate the potential benefits of incorporating RWD data into pavement management.

Beyer, Richie Addressing Pavement Preservation for Local Agencies The need for good stewardship while faced with resource limitations has placed local road professionals on the front line of pavement preservation. Local governments rely on partnerships to leverage resources and knowledge to deliver efficient and cost effective services to the citizens they serve. Mr. Beyer, a past president of NACE and currently NACE’s liaison to the NCPP, will be discussing the importance of local government partnerships with NCPP and industry, and how the partnerships benefit local government efforts with pavement preservation.

Block, Edgardo

(and Pat Kennedy, Scott Schram, Jon Wilcoxson) Panel Discussion: Impact of MAP-21 Performance Measures on Agencies MAP-21 (and its successor, the FAST Act) require that state surface-transportation agencies set and achieve performance targets for the National Highway System, and that they achieve minimum condition levels (a maximum percent poor not to be exceeded) on their Interstate systems. The discussion focuses on what state and local agencies see as key factors impacting their ability to fulfill MAP-21 requirements, and how they are approaching the challenge. Topics of discussion will include sustaining performance over the long term; addressing urban pavements; preparing for the data collection effort; coordinating data collection, target setting, and reporting for NHS roads outside a state DOT’s jurisdiction; and the central role that pavement preservation plays in effectively achieving performance.

Evaluating the Effect of Preservation Treatments on Pavement Performance & Service Life

Using PMS to Develop a Transportation Asset Management Plan

Pavement preservation is a mechanism for maintaining and improving the functional condition of an existing pavement, which involves the application of treatments that prevent the intrusion of moisture, slow deterioration or correct localized defects. In simpler terms, this means deferring the need for costly pavement rehabilitation or reconstruction. However, pavement preservation is not intended to increase the structural load carrying capacity of the pavement. This presentation discusses the use of the data from several transportation agencies and the U.S. Long-Term Pavement Performance program to model the effects of common preservation treatments on the immediate pavement condition and on the long-term pavement performance. Additionally, this presentation details how the resulting models can be used to demonstrate the effect of preservation on pavement performance, service life, and lifecycle costs. Finally, the presentation describes a number of data issues that were encountered, along with some techniques to overcome those issues.

Coplantz, John Examples of Strategic-, Network-, and Project-Level Decision Support Using Pavement Management Data Pavement management data support agency decisions at three different levels: strategic, network (tactical), and project (operational). This presentation will illustrate examples of how pavement management data support decision making on all three levels at the Oregon Department of Transportation (ODOT). ODOT uses pavement management data at the strategic level for pavement condition performance measures and target setting, evaluating funding impacts, and developing overall pavement preservation strategy. At the network level, pavement management data are used for funding allocations, identifying and selecting pavement preservation and rehabilitation projects, and initial scoping. Finally, at the project level, pavement management data are used to refine project scope, supplement field data collection activities, and to develop practical and cost-effective pavement designs for preservation and rehabilitation projects.

This presentation will discuss the requirements for an asset management plan and the specific portions for which the Pavement Management System was critical. Three components of the TAMP are described in some detail: itemization and condition of assets, gap analysis, and system-level life cycle cost analysis. The presentation will show results from the analyses and how the results will impact the 10-year financial plan.

Cross, Steve Best Practices for In-Place Recycling The Asphalt Recycling & Reclaiming Association’s (ARRA) primary function is to promote and disseminate technical information on the recycling of existing roadway materials through various construction methodologies, preserving limited natural resources and reducing costs. ARRA’s core recycling disciplines include cold planing, hot in-place recycling, cold recycling (cold in-place and cold central plant) and full depth reclamation. This presentation will focus on providing the audience with a brief overview of ARRA’s recycling disciplines and discussing the resources ARRA, along with others, have developed to support the successful design, construction and performance of in-place recycled pavements. These resources include the Basic Asphalt Recycling Manual, best practice guidelines, web-based inspector training classes, and regional and local in-place recycling seminars.

de Leon Izeppi, Edgar SCRIM Friction Testing in the USA The Acceptance Testing and Demonstration of the Continuous Friction Measurement Equipment (CFME) is a Federal Highway Administration (FHWA) project to facilitate the implementation of pavement friction management (PFM) programs to help support the Vision of working “Towards zero deaths and serious injuries on the Nation’s roadways.” Such programs involve the regular monitoring of pavement friction on the highway network and the use of friction and macrotexture thresholds that are linked to key safety performance measures. PFM programs are expected to make a significant contribution to selecting and maintaining the most appropriate (and cost-effective) pavement surfaces to increase highway safety by reducing crashes and their severity.

Diefenderfer, Brian Building Sustainable Pavements in Virginia Using Pavement Recycling The Virginia Department of Transportation is a national leader in the research and implementation of pavement recycling technologies. VDOT has recycled pavement sections on high volume test roads and completed projects on its interstate and primary systems. This presentation will focus on the latest laboratory test findings from NCHRP 9-51 (Material Properties of Cold In-Place Recycled and Full-Depth Reclamation Asphalt Concrete for Pavement Design), a five-year performance evaluation of the Interstate 81 pavement recycling project, and a summary of the results from test sections at the National Center for Asphalt Technology after one-and-a-half track cycles. In addition, the latest work on specification development and future applications of pavement recycling for construction and rehabilitation of high-volume roadways will be discussed.

Dietz, Jason Preserve Your Roadway Network Highway networks in the United States have been suffering from poor operational and structural condition states for several decades. The consequent congestion has caused large amounts of delay, fuel consumption, greenhouse gas emissions, and safety issues. With limited funding available, management of congested highways has become more challenging due to higher rates of deterioration and higher user costs. Therefore, transportation agencies and local agencies need to place more emphasis on innovative pavement preservation treatments at the right time (when), on the right project (where), with quality materials and construction (how) to help meet pavement performance expectations. This innovation helps deploy an array of different analyses, treatments and construction methods to help owners achieve and sustain a desired state of good road repair in a fiscally constrained environment.

Domonkos, Richard Indiana’s Local Technical Assistance Program (LTAP): Program Challenges & Successes The path to successful pavement preservation for local agencies begins with a good understanding of the concepts of asset management. Many pavement preservation treatments have failed prematurely because they were unsuitable, used in the wrong place, or at the wrong time.

When Indiana’s LTAP began the effort to train local agencies on how to develop a successful pavement preservation program, the role of asset management or specifically pavement management became apparent. It is important for pavement managers to understand the deterioration cycle of a pavement in order to successfully apply a pavement preservation treatment. Indiana’s LTAP began an annual effort to train local governments on how pavement preservation treatments are selected within a pavement management plan. This has culminated in a first-of-its-kind $150 million dollar annual road funding grant program for local governments. The grant program is contingent upon communities developing an asset management plan that includes a five-year pavement treatment plan.

Donnelly, Kevin Sustainable Pavement Practices Help Local Agencies in California Improve Their Road Infrastructure When performing certain types of road construction work agencies are influenced by many factors, such as funding, construction costs and availability of materials. But many agencies in California have been faced with a new challenge during a time when budgets are shrinking and they are working hard to maintain their deteriorating systems. State and Federal mandates for Green House Gas (GHG) Reduction have caused one agency, Los Angeles County, to develop a program focused on reducing GHG, reutilizing assets and increasing the overall system condition of the county’s roads. By keeping good roads good, using recycled materials in treatment selections, and reutilizing existing materials in-place whenever possible, the county has been able to meet these challenges. Since its inception in 2009, this sustainable system approach has saved $30 million, treated more lane-miles with less, raised the county Pavement Condition Index (PCI) and reduced GHG emissions by 80%.

Eberly, Rex (and Larry Galehouse) Advancing Pavement Preservation through Certification In 1976, AASHTO endorsed highway construction certification programs for use on a voluntary basis by State Departments of Highways and Transportation. Since then, certification programs have been widely adopted by agencies to address the proper construction of asphalt, concrete, and soils in highway applications. In recent years, a substantial number of agencies have adopted

speaker abstracts a pavement preservation philosophy to keep good pavements in good condition. However, many agencies and contractors may lack the technical knowledge and work experience in the many pavement preservation treatments available today. Consequently, successful construction and performance reliability are greatly dependent on expertise that is often lacking. Unnecessary failures occur that could have been prevented with targeted training of construction and inspection staff and implementation of certification programs for pavement preservation treatments. This year, the AASHTO TSP·2 Oversight Panel endorsed a pavement preservation certification program for individual treatment applications. This presentation gives insight into a comprehensive certification program and provides an industry perspective of why certification is necessary today for contractors and agencies alike.

Epps, Jon Dispute Resolution Disputes sometime arise between public agencies (owners), contractors, and materials suppliers on pavement preservation projects. These disputes need to be resolved in a timely manner and usually require the public agency, contractor, and material suppliers to hold a number of meetings and/or exchange information. The best approach to solving problems is to address the likely issues prior to the start of construction. Some approaches are discussed in the presentation. Disagreement between the owner and the contractor over test results is common. Test result variability is often a major reason for this disagreement. Sources of variability associated with testing are discussed. Specifications need to contain realistic limits with consideration given to sampling, testing and true materials/construction variability. Materials and construction variability are the only variabilities of the three that can affect performance. If issues occur during construction, resolution should be reached as soon as possible. All parties realize that “time is money.”

Feda, Jim Pavement Preservation Certification in South Carolina This presentation will cover the challenges that were faced during the development of South Carolina’s certification program; where we are today; and where we are going.

certified and the benefits that have been realized from this certification program.

Galehouse, Larry (and Rex Eberly) Advancing Pavement Preservation through Certification In 1976, AASHTO endorsed highway construction certification programs for use on a voluntary basis by state Departments of Highways and Transportation. Since then, certification programs have been widely adopted by agencies to address the proper construction of asphalt, concrete, and soil engineering in highway applications. In recent years, a substantial number of agencies have adopted a pavement preservation philosophy to keep good pavements in good condition. However, many agencies and contractors may lack the technical knowledge and work experience in the many pavement preservation treatments available today.

Galehouse, Neal Societal Benefits of Pavement Preservation The highway system in the United States has dramatically changed society forever. It has given people the freedom of mobility to any destination throughout the country at whatever time they desire. It has positively influenced economic growth, international competitiveness, and been a crucial factor in national defense. Travel time reliability of shipments has made “just in time” delivery more feasible by reducing warehousing costs and adding to manufacturing efficiency. It has broadened the options of shoppers by increasing retail competition, resulting in larger selections and lower consumer prices. Yet many people take the highways for granted. This presentation will illustrate the societal benefit of highways and what can be lost if our nation fails to preserve the investment made in our highway system by previous generations.

Decision-Making: Putting Data to Work

Recognizing Life Cycle Cost Sensitivity for Pavement Preservation Treatments

This presentation will discuss how the RTC (Regional Transportation Commission), an MPO in Reno, Nevada, uses pavement management and other data to manage and optimize the benefits to the pavement network and the pavement preservation program. The agency has an ongoing research contract with UNR (the University of Nevada at Reno), which is home of the Western Region Superpave Center. Research into the performance of local materials and the application of national studies like those from NCHRP to local conditions, have led directly to the implementation of material use, treatment types, and timing to dramatically improve pavement performance. Examples will be given of the use of polymer-modified hot mix, lime-treated aggregates, optimal timing of preventive maintenance treatments, and cape seal performance.

Goodspeed, Charles New Hampshire LTAP Advancing Pavement Preservation The NH Technology Transfer Center, as part of their transportation infrastructure asset management project, “Statewide Asset Data Exchange System” (SADES), is offering asphalt wearing surface preservation courses to municipal engineers, Regional Planning Commissions, and DOT engineers responsible for assessing and/or maintaining highway networks. The road management program consists of an iPad field condition data entry menu using cloud storage, alternative repair strategies as a function of 10 field deterioration conditions, an iPad repair work reporting program, and a forecasting program using $/service life parameters. The preservation training covers procedures, costs and service life projections for many of the wearing surface repair alternatives. As part of the preservation effort the Technology Transfer (T2) Center is also addressing financing highway infrastructure sustainability. The approach being taken is levying a user fee based on vehicular GVW and average gas mileage. A user fee will be based on these parameters read by a chip on a vehicle at the pump for fuel and hybrid vehicles and through voltage meters and WiFi for electric cars. A pilot program is being prepared for DOT and university vehicles.

This presentation will focus specifically on highway pavement economics in the US, New Zealand, and Canada. Pavement life cycle cost analysis (LCCA) seems to be the most controversial. Thus, it is critical to recognize the LCCA sensitivity issues. The overarching challenge that must be addressed is the validity of classical engineering economic theory where the LCCA outcome is deemed fair and objective if the alternatives are compared over the same period of analysis using the same interest rate. A close study of the methodology and the sensitivity to LCCA inputs will show that this only applies to comparison of alternatives that have similar technical aspects and roughly similar service lives. When the theory is applied to the comparison of asset alternatives that have radically different technical aspects and dissimilar service lives, some of the fundamental assumptions made in engineering economics no longer apply and the output is questionable.

Hall, Geoff Maryland’s Perspective on Pavement Condition Data for Pavement Preservation How long do pavement preservation treatments last? What is needed to expand the use of pavement preservation treatments? The answers lie in having the right types of quality condition data. Transportation agencies have historically focused on fixing their worst roads first—fixing roads that are too far gone for pavement preservation. It was difficult to justify fixing anything besides the worst roads. In order for pavement preservation projects to have a fair chance at getting a slice of the funding pie, agencies must use an asset management approach that includes selecting a mix of good, fair, and poor roads for repair— not just the worst. This requires preservation-focused and reliable condition data. Without it, preservation would not be cost-effective, even if overcoming the odds against being chosen. This presentation will focus on the types and quality of condition data needed to effectively implement pavement preservation alongside rehabilitation.

speaker abstracts approach to maintaining an existing highway system before the onset of serious payment distresses. The importance of having a proper preservation strategy and trigger values in place will be covered, describing how application of the cost-effective treatment at the right time, to the right pavement, at the right cost will result in longer-lasting pavements. Application of a cost-effective treatment in a timely manner will restore the pavement almost to its original condition and by doing so, the cumulative costs of such treatments are substantially less than reconstruction or major rehabilitation over the life of the pavement. The expected performance of the treated pavement will be discussed along with the availability of information, utilizing a pavement management system.

Harvey, John Preservation & Quality of Life: Framework & Examples Pavement preservation treatments can have effects on human quality of life other than reducing the cost of keeping a pavement in operable condition and improving the ride quality and safety of motor vehicle road users. This paper identifies a framework for considering where preservation treatments affect other aspects of quality of life, and for other than motor vehicle users. The paper provides a brief overview of some California studies on several of these aspects. The paper then provides details of the California tire/pavement laboratory and field noise study for asphalt and concrete pavements as an example, implementation to date, and research that is currently underway.

new techniques or products that may improve results or cut costs. Alternatively, experimentation has risks. Failures often result in brutal public feedback and abandonment of materials and techniques without due analysis to find out what went wrong. Learn how NDLTAP encourages innovative approaches open new avenues to pavement preservation while limiting the downsides of experimentation.

Hein, David (and Don Reid) Adapting Pavement Preservation Strategies to Significant Changes in Economic Conditions Pavement preventive maintenance is important for preserving the municipal road infrastructure. Preventive maintenance treatments extend the lives of pavement assets by preventing or retarding the progression of pavement distresses that will lead to premature deterioration of the entire pavement asset. Further, preventive treatments are very cost effective because they extend the life of the pavement without the high cost of repaving. But what happens when a significant economic event occurs changing the operating conditions within an agency? The impact could be either positive (extra funding for roads leading to a stadium) or negative (a natural disaster). This presentation is a case study of the impact from the 2010 Metro Nashville, Tennessee, flood on the condition of the road network and steps taken to adjust Metro’s pavement preventive maintenance strategies to mitigate the impact of the flood on Metro’s pavement assets.

North Dakota: Innovation Building Blocks

Innovative Concrete Preservation Practices Used in California

North Dakota’s Local Technical Assistance Program (NDLTAP) uses several approaches to encourage innovation among local leaders. Helping them break out of stagnation increases their arsenal of solutions and tools. They expand their understanding of possible solutions and develop their own pavement preservation techniques tailored specifically to local needs, budgets, and conditions. NDLTAP uses conference presentations, classes, technical announcements, and funding opportunities to help local leaders live the adage that “innovation is local.” While many local agencies do their best to sift through application techniques, materials, life cycle costs, etc., establishing a broad-spectrum pavement preventative maintenance program is a challenge. Basing future approaches on past success limits adoption of

Innovation in a large, resource conscious agency remains an ongoing challenge. California maintains approximately 15,000 ln-mi of concrete pavement, most of which must be repaired within narrow closure windows due to urban traffic demands. Innovative rapid strength gaining materials alone are not always sufficient to produce durable, long-lasting repairs. Readily implementable design features such as tapering spall repair edges and reinforcing or doweling replaced slabs can extend performance life for little added cost. Where failure mechanisms are complex or project conditions warrant a specialized solution, California has had some success using higher cost materials such as polyester concrete for spall repair and dowel bar retrofit or precast concrete for slab replacement.

Ishee, Mark Keys to a Successful Pavement Preservation Program Pavement preservation programs generally require some amount of time to gain traction and Program Managers are often pressed to justify their decisions. Ultimately, the program’s value must be proven to agencies and to taxpayers who fund the program and live with the results on a daily basis. The preservation community’s collective experience can help to assure successful application of treatments and provide insight on information that can be communicated to demonstrate benefits of a program. In the same way that employing more of the accepted “best practices” of an individual preservation treatment improves the likelihood of an effective application, the more of these keys one can accomplish, the better one’s chances are of having a sustainable preservation program.

Jerman, Bob Ensuring Quality Mix Designs Ensuring quality mix designs for slurry surfacing systems, both slurry seal and micro surfacing, should be of interest and an objective of every participant in this area of pavement preservation. To do so, both the tangible and intangible perspectives in accomplishing this common objective will be explored in the presentation. The tangible aspects of delivering quality mix designs will be presented along with a brief discussion on the critical intangible aspects of ensuring quality mix designs. The tangibles will focus on raw material selection, including overviews of specification requirements for the emulsified asphalt, aggregate, mineral filler, water, and additives. Qualification and system performance specifications and evaluations will focus on those currently available in the ISSA A105 Recommended Performance Guideline for Emulsified Asphalt Slurry Seal, the ISSA A143 Recommended Performance Guideline for Micro Surfacing, and AASHTO’s PP083-16-UL Provisional Standard Practice for Micro Surfacing Design. The intangibles are not typically documented or generally addressed during organized industry exchanges but will also be included as part of this presentation.

course, decreasing skid numbers, and increasing wet weather accidents. Funding did not exist for traditional removal and replacement options, so the agency elected to use pavement texturing and rejuvenation techniques to extend the pavement life. This presentation describes the approach used, including the use of performance specifications. Wet weather accident history is presented for a period of three years prior to the project, and three years after project completion that exhibits significant safety improvements.

The discussion focuses on what state and local agencies see as key factors impacting their ability to fulfill MAP-21 requirements, and how they are approaching the challenge. Topics of discussion will include sustaining performance over the long term; addressing urban pavements; preparing for the data collection effort; coordinating data collection, target setting and reporting for NHS roads outside a state DOT’s jurisdiction; and, the that pavement preservation central role plays in effectively achieving performance.

Kinney, Todd Addressing Pavement Preservation for Local Agencies Many local road professionals tasked with pavement management are quickly becoming cognizant of the benefits and necessity of pavement preservation. Mr. Kinney will discuss NACE’s perspective on the importance of pavement preservation to counties and local road professionals. NACE members face issues involving educational policy and funding by decision makers. Mr. Kinney will also provide a summary of the major accomplishments of the NACE Pavement Preservation committee in prioritizing pavement preservation activities and will also describe information on current best practices and innovative techniques NACE provides to its members.

speaker abstracts Latham, Andrea Micro Milling: Applications & Advantages for Pavement Preservation With massive budget shortfalls and the need to maintain and improve existing infrastructure, much emphasis is placed on pavement maintenance and preservation. Micro milling in conjunction with pavement preservation applications can offer a fresh approach to traditional resurfacing methods. Micro milled surfaces share many of the same benefits as traditional milled surfaces such as: restoring surface ride, preserving existing curb lines, providing a better bonding surface, and generating RAP (Recycled Asphalt Product). By adding these benefits to thin lifts, micro surfacing and slurry seal applications, which are typically only used as an overlay, states are able to stretch their maintenance resources further. Andrea Latham of Keystone Engineering will share the benefits of incorporating micro milling into various pavement preservation techniques, distinguish the differences between micro and standard milling, and compare various state micro milling specifications.

Luhr, David Performance Measures for Making Pavement Preservation Decisions The new MAP-21 legislation states that “Performance management will transform the Federal-aid highway program. . . .” So, how can performance measures and performance management be used to make pavement preservation decisions? Those decisions relate to the right time for the right treatment at the right place. By monitoring pavement conditions and having the ability to track costs, an agency can develop performance measures that evaluate the cost-effectiveness of preservation treatments. Procedures can be developed for determining the right time for applying different preservation treatments, depending on the costeffectiveness and expected performance. Performance measures can also be used to communicate to executives and legislators how well pavements are being managed and the benefits of pavement preservation.

applications. This presentation provides insight to other environmentally beneficial uses for which agencies are using RAP as a replacement aggregate in slurries, micro surfacing, chip seals and cape seals.

McDaniel, Becky Sustainability Benefits of Pavement Preservation This presentation will highlight how pavement preservation provides benefits in terms of sustainability. It will also include considerations of how the materials chosen for preservation treatments can increase those sustainability benefits. For example, the use of recycled materials or by-products—which are routinely being used in pavement construction—also can be and are used in pavement preservation, offering good performance, cost effectiveness and conservation of resources.

Metcalf, Scott Newest Advancements in Slurry Seal & Micro Surfacing This presentation will cover the value of using slurry seal and micro surfacing treatments. it will then focus on covering the newest advancements in polymer modification, new testing of the emulsions using Multiple Stress Creep and Recovery (MSCR) and mixes using Cantabro Testing. We will review the performance of highly modified (HiMa) Micro Surfacing and Slurry Seal applications across the country and talk about some of the newest research to develop a more crack resistant micro surfacing treatment. We will cover the use of 100% recycled asphalt/reclaimed aggregates. We will discuss ground tire rubber additives used in slurry seal and micro surfacing projects. These advancements are leading to better performing, longer lasting, “greener” surface treatments that will lead to longer lasting roads.

Miller, Rick So Many Choices, So Much Data Pavement preservation is not a new concept. neither is pavement surface data collection. However both pavement preservation activities and pavement surface data collection have expanded over the years. What was once a binary choice to leave a pavement alone or reconstruct is replaced today by a range of preservation, rehabilitation, and reconstruction options. Likewise, pavement condition data were once nearly binary in that they could be summarized as the pavement

is satisfactory or it should be reconstructed. Today, pavement condition can be assessed using a variety of measurements and analysis from those measurements, typically summarized as roughness, cracking, rutting, and faulting. The objective today is to be able to use all of those surface condition data and evaluate them to determine appropriate pavement treatments. This presentation will follow the experience by one DOT in moving from manual, small sample pavement surface condition measurement to automated measurement and analysis.

Miller, Todd Addressing Pavement Preservation for Local Agencies “Get Missouri out of the mud!” was a campaign slogan in 1920 to pass a $60 million bond to develop an oiled surface farm-to-market roadway system in Missouri. In 1952, Missouri took over almost 12,000 miles of county highways, bringing 95% of its citizens to within two miles of a paved road. Today, Missouri takes care of over 33,000 miles of roads. Many of these roads carry little traffic and are typical of county road systems in other states. Over the past 20 years, the Missouri DOT has made annual system condition assessments which have revealed trends and enabled comparisons of investment levels and strategies. All of this information is now available at the touch of a button on the agency’s browserbased Transportation Management System. The backbone of this system is a linear referencing scheme containing the geospatial locations of all state routes in both directions. With this common system, information can be mapped and compared with many other features. This system allows Missouri to effectively communicate how it will invest future tax dollars and how those investments will impact the condition of its transportation system.

Naras, Ed UTBOs, Fog Seals & Rejuvenators: MassDOT’s Experience SHRP2 R-26 presented opportunities for states to showcase various preservation techniques. In its project, MassDOT showcased Ultra-thin Bonded Overlays (UTBO), fog seals and rejuvenating seals on a roadway having traffic volumes in excess of 100,000 vehicles per day. A total of ten treatments were showcased on this 1.4M SY project which was completed in September 2015. Quality Assurance specifications, including targets for ride quality were utilized on this project and are part of its ongoing assessment.

Nichols, Jim Nevada’s Local Technical Assistance Program (LTAP) Efforts to Advance Pavement Preservation Nevada is a large state with two population centers, Reno and Las Vegas, and 17 counties and small towns separated by vast distances. The LTAP training program consists of offering courses throughout the state emphasizing safety, workforce development and infrastructure management. Every year we take a road trip to agencies to identify their problems such as budgets, distresses and conditions and possible fixes. We put on up to 10 related courses per year on pavement preservation and maintenance and work with Nevada DOT to organize maintenance academies for workers and supervisors. One of our goals this year is to coordinate “show and tell” sessions for cities trying new procedures and/or materials. Personnel from other nearby towns would be invited to attend and learn from the host agency’s experience with the new technology.

Nowaczyk, Tracy (and Chad Shive) Modernizing Pavement Management with Automated Data Sources & Decision Analysis The Kentucky Transportation Cabinet (KYTC) historically used a visual evaluation system (VES) to assess the condition of pavements. Recently, KYTC began operation of a three vehicle fleet of asset collection vans equipped with the Laser Crack Measurement System (LCMS). With the ultimate goal of complete data migration into automated crack detection, KYTC began work with the University of Louisville to develop a data mapping method. The model created will transform data from the LCMS to the existing VES format to allow legacy data and models to be used in pavement management. Additionally, the university has worked with the Cabinet to develop a composite index to provide an objective descriptor of pavements and allow the prioritization between alternative projects. This work will remove subjectivity and move the Cabinet toward the next generation of pavement management.

Peshkin, David Pavement Preservation on Highly Trafficked Roads: The New Normal The most common use of treatments associated with pavement preservation has been on lower volume roads. There are many explanations for this: budgets

speaker abstracts are smaller for these roads, there is less risk, there are many more miles of these roads, and small agencies have more flexibility to try different options. The SHRP2 R26 project explored preservation on heavily trafficked, or higher volume, roads, and identified many agencies which already do this successfully. Their experiences were turned into guidelines that others could follow to extend their own practices. When FHWA/AASHTO moved to support SHRP2 implementation, this study was one of the first to be promoted and 14 agencies received funding to advance their practice of preservation on high volume roads. This presentation discusses the implementation of preservation practices for high volume roads and how this is becoming the “new normal” for many agencies. It discusses how this practice will continue to grow and also how agencies might improve their practice of preservation on high-volume roads.

Pilson, Charles Trade-off Considerations within the Context of Pavement Management Trade-off is essentially finding the right balance between a number of solutions. Trading off between different longterm treatment strategies for maintaining roads has long been at the core of pavement management. Intuitively, we are now convinced that preservation is key, but what should be the strategy for roads that are no longer preservation candidates? This presentation explores the trade-offs between long-term strategies across the spectrum from preservation to reconstruction.

Powell, Buzz NCAT Preservation Treatment Findings For the last 16 years, the NCAT Pavement Test Track has performed full-scale, accelerated performance research to reduce the life cycle cost of flexible pavements. Experiments are designed in three-year research cycles to generate practical, rapidly implementable findings that best meet the mix, materials, and structural pavement research needs of state DOTs. In 2012, off-track test sections were built on a nearby low-traffic road (Lee Road 159) in order to precisely quantify the benefits of a consensus array of pavement preservation treatments and treatment combinations. In 2015, findings from Lee Road 159 were utilized to design and build a larger, more comprehensive experiment on a nearby high traffic roadway (US-280). Weekly roughness, rutting, texture, and cracking data are utilized to objectively quantify the short and long term life extending and

Rada, Gonzalo Update on Proposed FHWA LTPP Pavement Preservation Experiments Pavement preservation technology has been around for decades and it has been proven, mostly anecdotally, to be an effective approach to extend service life and improve safety and service condition. Pavement performance is at the heart of the preservation decision-making process. As such, provision of performance data on in-service pavement test sections where controlled applications of treatments are monitored, is the motivation for the planned LTPP SPS-11 Asphalt Concrete and SPS-12 Portland Cement Concrete pavement preservation experiments. The objective of these experiments is to establish the impact of timing of preservation treatments on distress propagation rates, which will enable determination of their impact on pavement life extension and performance. In turn, this information will enable determination of the right timing and cost-effectiveness of preservation treatments. This presentation describes the experiments and supporting information developed to facilitate their deployment. It also discusses the funding and management plans for the experiment.

Rathbun, John Using Hot In-Place Recycling to Ensure Success This presentation will focus on the project selection criteria that should be used to select a pavement candidate for hot in-place recycling (HIR). All current methods of HIR will be presented and examined, including surface recycling, repaving, and remixing. The presentation will touch on pavement candidates that should not be considered for HIR as well as the costs and benefits associated with an HIR project. A brief case study of a municipal HIR program will be presented as an example of the cost savings and environmental benefits that a properly designed and implemented HIR project can provide.

Reid, Don (and David Hein) Adapting Pavement Preservation Strategies to Significant Changes in Economic Conditions Pavement preventive maintenance is important for preserving the municipal road infrastructure. Preventive

maintenance treatments extend the lives of pavement assets by preventing or retarding the progression of pavement distresses that will lead to premature deterioration of the entire pavement asset. Further, preventive treatments are very cost effective because they extend the life of the pavement without the high cost of repaving. But what happens when a significant economic event occurs changing the operating conditions within an agency? The impact could be either positive (extra funding for roads leading to a stadium) or negative (a natural disaster). This presentation is a case study of the impact from the 2010 Metro Nashville, Tennessee, flood on the condition of the road network and steps taken to adjust Metro’s pavement preventive maintenance strategies to mitigate the impact of the flood on Metro’s pavement assets.

top surface layer (¾" to ⅞") without removing the largely sound underlying layer. The development of the new method, including the challenges, the pavement design, the tests, the processes of pavement preparation and quality control/acceptance developed to ensure good quality, the construction steps, the experiences learnt during the course of the projects will be presented. The new method has produced satisfactory results. The pavements on the I-75 and I-95 projects are still in good condition after 9 and 5 years, respectively. The average saving is approximately $60,000 per lane mile, and the total savings on both projects are more than $10 million, which is significant when compared to traditional pavement resurfacing methods.

Roberts, John Diamond Saw Cut Pavement Textures: Improving Pavement Performance and Customer Satisfaction Increasingly, specifiers around the world are recognizing the benefits of diamond saw cut pavement textures for their concrete and asphalt pavement and bridge deck surfaces. While most properly designed and constructed Portland cement concrete pavements (PCCP) can last for 30 to 50 years with minimal structural damage, functional issues such as ride quality, noise and skid resistance tend to manifest over time due to surface abrasion and subgrade settlement. In the past, agencies often relied on overlays to address these important issues affecting their pavements. Mounting experience has shown that concrete pavements can achieve their maximum longevity and performance through the use of diamond saw cut pavement textures. This presentation will: (1) Outline the basic procedures involved in the diamond saw cut texturing process, (2) highlight the benefits and uses of diamond saw cut pavement textures, (3) review key research initiatives related to diamond saw cut pavement surface textures with a focus on friction improvement and accident reduction, and (4) discuss performance and costs as reported by public authorities.

Robinson, Ernay (and James Tsai) Georgia DOT Micro Milling The Georgia DOT developed a new pavement preservation method (using micro milling and a thin overlay) to cost-effectively replace the deteriorated thin open-graded

Legislation passed in California requires the state to reduce its greenhouse gas (GHG) emissions to 1990 levels by 2020. For transportation, this legislation has spawned comprehensive “green initiatives” such as region-wide bike share programs, electric vehicle charging stations, and incentives for zero emission fleets. But will this be enough? To be successful, it is not enough to seek new ideas, but to also search for innovative alternatives to existing practices. The San Francisco Bay Area’s 43,000 miles of local roadways, much of which are in need of repair, provide an opportunity to examine existing maintenance methods and revise traditional practices to help meet environmental goals. The Metropolitan Transportation Commission has been working with local jurisdictions to incent and initiate environmentally sustainable technologies and practices in road maintenance. This presentation will detail some of the past successes and ongoing efforts in this area.

Schram, Scott

(and Edgardo Block, Pat Kennedy, Jon Wilcoxson) Panel Discussion: Impact of MAP-21 Performance Measures on Agencies MAP-21 (and its successor, the FAST Act) require that state surface-transportation agencies set and achieve performance targets for the National Highway System, and that they achieve minimum condition levels (a maximum percent poor not to be exceeded) on their Interstate systems. The discussion focuses on what state and local agencies see as key factors impacting their ability to fulfill MAP-21 requirements, and how they are approaching the challenge. Topics of discussion

speaker abstracts will include sustaining performance over the long term; addressing urban pavements; preparing for the data collection effort; coordinating data collection, target setting and reporting for NHS roads outside a State DOT’s jurisdiction; and, the central role that pavement preservation plays in effectively achieving performance.

Schwartz, Charles Structural Characteristics & Environmental Benefits of Cold-Recycled Asphalt Paving Materials Cold recycling is a viable and economical rehabilitation strategy for many asphalt pavements. However, quantitative values for the engineering properties of these materials for use in pavement structural design are lacking. Measurement of these structural properties is problematic as it is difficult to realistically simulate the significant effects of field curing. Cores of foam- and emulsion-stabilized cold recycled materials were obtained from more than 25 projects across the United States and Canada after 6 to 12 months of field curing. Dynamic modulus and permanent deformation properties were measured using a novel small-specimen subcoring technique. The measured dynamic modulus values of field-cured cold recycled materials approached and the permanent deformation properties were generally comparable to those of convention hot mix asphalt (HMA) base mixtures. Analyses using the mechanistic-empirical pavement design guide showed generally satisfactory predicted performance for the cold recycling as compared to conventional HMA overlays. Cold recycling processes also provide environmental benefits of reduced greenhouse gas (GHG) emission reductions from increased use of recycled vs. virgin aggregates, reduced added asphalt content, savings of energy from heating aggregates, and for in-place recycling processes, reduced transport between the production plant and the job site. Comprehensive cradle-to-grave greenhouse gas analyses showed a net 25% to 55% average reduction in GHG emissions for cold recycling compared with conventional HMA overlay rehabilitation.

Scofield, Larry Survey of State Pavement Management Practices for Concrete Pavements Twenty states were recently surveyed to explore pavement management practices for concrete pavements. The survey investigated the organizational

setting of PMS units, their structure, preservation funding sources, PMS distress data collection equipment, software, and procedures, and PMS program development and operation. The survey results provide insight into the equipment and procedures used by states to develop concrete pavement preservation strategies. An attempt is made to portray what percent of projects are triggered by each of the intervention models to better understand the failure modes of concrete pavements so that more effective preservation strategies can be pursued.

Shields, Todd Basics of Quality Assurance Federal regulations require quality assurance procedures, but what does that really mean for a pavement preservation project? This presentation will cover the basics of a quality assurance program, define the responsibilities of agencies and contractors, examine the steps taken at each phase of construction, and outline the elements of a good quality control plan.

Shive, Chad (and Tracy Nowaczyk) Modernizing Pavement Management with Automated Data Sources & Decision Analysis The Kentucky Transportation Cabinet (KYTC) historically used a visual evaluation system (VES) to assess the condition of pavements. Recently, KYTC began operation of a three-vehicle fleet of asset collection vans equipped with the Laser Crack Measurement System (LCMS). With the ultimate goal of complete data migration into automated crack detection, KYTC began work with the University of Louisville to develop a data mapping method. The model created will transform data from the LCMS to the existing VES format to allow legacy data and models to be used in pavement management. Additionally, the University has worked with the Cabinet to develop a composite index to provide an objective descriptor of pavements and allow the prioritization between alternative projects. This work will remove subjectivity and move the Cabinet toward the next generation of pavement management.

Shuler, Scott Best Practices with Chip Seals Pavement preservation is a means for maintaining or improving the condition of an existing pavement. Pavement preservation is not expected to substantially

increase structural capacity of a pavement. However, pavement preservation provides equal or improved pavement performance by maintaining the condition of the pavement structure, thereby increasing service life. Chip seals have been shown to provide one of the most cost effective means to accomplish preservation of flexible pavements. Consequently, chip seals are often used for pavement preservation. However, chip seals are not universally loved and sometimes have been banned outright by agencies. The reason for this is often because of premature failure of the seal, vehicle damage, or both. This presentation will provide the basic information necessary for designing and constructing successful chip seals. By following these fundamental processes agencies can avoid premature failure and vehicle damage and add one more cost effective pavement preservation treatment to the toolbox.

Snyder, Mark Concrete Pavement Reuse & Recycling: Proven Technologies! Concrete pavement recycling is a proven technology that offers an alternative aggregate resource—recycled concrete aggregate (RCA)—that is both economical and sustainable. Concrete recycling for paving applications is now performed in at least 41 states and U.S. production of RCA averages more than 140 million tons per year. The primary application of RCA has been subbase materials, but it also has been used in concrete and asphalt concrete paving layers, embankment and other applications. This presentation will describe concrete pavement recycling practices and will present current thinking concerning the use of RCA in concrete paving mixtures and subbase layers, along with appropriate pavement design modifications and best construction practices when using RCA in paving applications. Case studies will be used to illustrate the behavior and performance of pavements constructed using RCA in various ways, including the use of RCA from pavements suffering from D-cracking and Alkali Silica Reaction (ASR).

Soneira, Casey Introduction to AASHTO Accreditation Quality and accountability are key factors to the successful maintenance of our infrastructure. One of the tools used to recognize quality and boost confidence in materials testing is accreditation. The accreditation process can help propel your lab to a higher level of quality, and gain national recognition for that achievement. Accreditation can even give your laboratory

a competitive edge. This presentation will discuss the importance of quality management, introduce you to AASHTO re:source’s three main programs, and outline the AASHTO Accreditation process.

Stephanos, Peter Implementation of MAP-21 Performance Measures & Asset Management Plan This presentation will provide an overview of proposed and final Federal regulations that have been put in place to implement new performance requirements for the Federal-aid Highway Program. The presentation will focus on infrastructure condition and asset management plan requirements as well as implementation activities underway and planned to support transportation and planning agencies as they work to comply with the new requirements.

Tan, Sui Making Better Decision by Linking Americans with Disabilities Act (ADA) Curb Ramps to PMS Data By now, if your pavement preservation toolbox has micro surfacing or cape seals, you will be dealing with updating curb ramps to be ADA compliant. The US Department of Justice, in the ruling released in July 2013, required that any pavement alterations will need to have a new curb ramp installed if it is not meeting the requirement. Are you caught off guard? Are you avoiding those treatment strategies that will trigger ADA compliance? Are you reducing your project limits due to additional compliance costs? If you are answering yes to most of the questions, then it is time to be proactive in project planning so that you are not compromising your pavement preservation efforts while still meeting ADA curb ramp requirements.

Thomas, Todd Impacts of Pavement Preservation and Recycled Materials on Sustainability There are several points of opportunity in the pavement life cycle to make positive sustainability impacts with preservation treatments and the use of recycled materials. This presentation focuses on the individual items in the pavement life cycle—flexible pavement design, materials, construction, operations, maintenance and rehabilitation, and reconstruction—and how recycling, preservation, and new procedures can improve sustainability for each. With each of these items, however,

speaker abstracts there are gaps between what is possible and what is actually practiced. There are also improvements to some current design practices to make gains for sustainability. These issues are presented, along with a few scenarios on energy and greenhouse gas emissions.

Tighe, Susan Evaluating the Economic Benefit of Pavement Preservation Various North American transportation agencies have implemented several preventative maintenance techniques to improve pavement performance and safety. In Canada, several municipalities and cities have been resurfacing with various preservation treatments for both asphalt and concrete pavements to improve the pavement surface condition. This presentation reviews the typical treatments that are being employed in various areas and discusses the technical and economic costs/ benefits of the various techniques based on research currently being conducted at the Centre for Pavement and Transportation Technology (CPATT) located at the University of Waterloo in Ontario, Canada. It also highlights the safety improvements that have also been observed as a result of the preservation treatments.

Uhlmeyer, Jeff SPS-2 Concrete Pavement Preservation Experiment The Long Term Pavement Preservation (LTPP) program was designed as a comprehensive 20-year study of in-service pavements. The Specific Pavement Studies (SPS) experiment constructed as part of this program, represents the most comprehensive concrete research ever undertaken. This experiment, designed to evaluate the long term performance of five design features, constructed 12 core LTPP test sections in each of 14 states which now range in age between 16 to 24 years. A seven state a pooled fund has recently been formed to develop a preservation experiment using the SPS-2 test sections. This leverages the original SPS-2 performance monitoring and forms the basis for the new experiment.

Wagner, Chris Save Lives with High-Friction Surface Treatments Maintaining the appropriate amount of pavement friction is critical for safe driving. Challenging conditions require a higher friction on the road surface than is necessary on a flat, straight section of highway. Additionally, in particular locations where vehicles often brake excessively, the standard road surface may become prematurely polished, thereby reducing the available pavement friction. HFSTs are pavement surfacing systems with exceptional skidresistant properties not typically provided by conventional materials. The spot application of a thin layer of durable, high-friction aggregates as a topping on specially engineered resin or a polymer binder affords long lasting traction, while making the overlay much more resistant to wear and polishing.

Wang, Kelvin Data Automation for Pavement Distress Survey in the 3D World The need for distress surveys at the pavement network level was apparent since the AASHO Road Test for various aspects of pavement engineering. Only in the last decade have there been rapid advances in data collection technologies for pavement condition. About ten years ago, 2D imaging, based on laser illumination started to be used in production at 1mm resolution which can be operated at highway speed, overcoming a major obstacle of image shadow due to sun light. A few years ago, 1mm

resolution 3D pavement surveys became a reality. This presentation discusses the progress of data collection technologies at the present and future innovations, and then focuses on the processing of collected visual data in 2D and 3D for distress results. Problems and limitations in data processing are discussed. Possible paths to model human intelligence and cognition are presented and initial tests show promise. The last technical material to be presented is about the potential to use deep learning to tackle the difficult problem of maintaining precision and bias levels for automated processing of distress data. The presentation concludes that pavement distress survey with full automation, at high speed, and at required and consistent precision and bias levels is a grand-challenge problem that needs substantial time and resources in the future.

Warner, John Green Chemistry & Commercial Applications Technology has advanced significantly over the past several decades. We have the ability to manufacture products with amazing complexity and diversity. But our manufacturing processes typically use high temperatures, high pressures and hazardous reagents to accomplish the synthetic transformations necessary. In natural systems we see products of even greater complexity and diversity, and yet they are “manufactured” in nature at room temperature, ambient pressure, using water typically as a solvent. Recognizing and understanding these “natural tendencies” allows one to design processes that have reduced toxicological and environmental impact. This presentation will describe results at the Warner Babcock Institute for Green Chemistry and Collaborative Aggregates that illustrate the application of the principles of green chemistry in commercial applications.

Worel, Ben Update on MnROAD Preservation Treatment Sites MnROAD and NCAT have recently partnered to work on two important national studies supported by state DOTs and Industry. The first is a study to develop a national cracking performance test for asphalt pavements and the second is to develop a better understanding of the performance and life extending benefits of pavement preservation techniques used throughout the country. This presentation will focus on the pavement preservation study which will study a common set of preservation techniques in which test sections have been built in Minnesota and Alabama on both low- and high-volume roads. This presentation will tie to the NCAT presentation, also given in this session by covering the construction completed in Minnesota and the progress and benefits this partnership has achieved so far for its supporters.
