Pavement Roadmap Problem Statements: Theme 4

The final product of the research is a best practice guide for pavement management. Not only will this be a reference for all things related to pavement management, but it will also act as a “desk guide” for practitioners. To enhance access and implementation, it is envisioned that this guide will be developed and available through an electronic web-based format.

Performance Specifications Strategic Roadmap: A Vision for the Future

In May 2000, the Florida Department of Transportation (DOT), in cooperation with the Federal Highway Administration (FHWA) and the National Partnership for Highway Quality, conducted a workshop on the future of performance-related specifications (PRS) in the highway industry. More than 50 Federal, State, and private sector engineers met to discuss the background, history, and future of this topic. The attendees agreed that the subject was important, extremely complex, and had to be addressed. They recommended a national strategy to identify and coordinate efforts, and FHWA agreed to initiate the process.

In December 2001, FHWA, in cooperation with the American Association of State Highway and Transportation Officials (AASHTO) and various industry associations, sponsored the first national PRS Technical Working Group (TWG) meeting. The purpose of the meeting was to establish the foundation for a PRS movement to foster the development and application of performance-related specifications. The PRS TWG identified a series of activities that lead to continued development and implementation of PRS. At that meeting, the mission was expanded to include the formation of expert task groups in various technical disciplines and to include warranties, which are clear and growing alternatives to PRS.

In November 2002, the PRS TWG met again to review work accomplished by the expert task groups and to discuss several additional aspects of PRS. The attendees reemphasized their support for the effort and suggested that method specifications be addressed in some format in the PRS mission. Noting that the mission had been expanded to include method specifications and warranties along with performance-related and performance-based specifications, the attendees also recommended that the name of the effort be changed to the Performance Specification Program.

This Performance Specifications Strategic Road Map is intended to be used as a tool to guide the highway community in developing, implementing, and accepting performance specifications as viable alternatives for highway construction. It is a working document that will be maintained by the FHWA on its website and periodically updated.

The Concrete Pavement Roadmap

The Concrete Pavement (CP) Road Map is a plan for concrete pavement research that will guide the investment of research dollars for the next several years. This TechBrief is a summary of FHWA-HRT-05-052 Concrete Pavement Road Map Volume I and FHWA-HRT-05-053 Concrete Pavement Road Map Volume II.

National Asphalt Roadmap: A Commitment to the Future

This report is a combined effort of the Federal Highway Administration (FHWA); American Association of State Highway and Transportation Officials (AASHTO), National Asphalt Paving Association (NAPA), Asphalt institute (AI), and the National Stone, Sand & Gravel Association (NSSGA).

This Roadmap is a comprehensive report, which addresses a full range of important challenges in asphalt technology. It serves as a guiding document for research and technology deployment organizations and for others involved in the identification and formulation of programs and projects. Individuals and groups are encouraged to draw upon and share this document.

National Asphalt Roadmap: A Commitment to the Future – Executive Summary

This report is a combined effort of the Federal Highway Administration (FHWA); American Association of State Highway and Transportation Officials (AASHTO), National Asphalt Paving Association (NAPA), Asphalt institute (AI), and the National Stone, Sand & Gravel Association (NSSGA).

This document is the result of public-private partnership and presents the shared vision of the asphalt community for research and technology in the field of asphalt pavement and material technologies. In addition to the contributing agencies and organizations recognized on the title sheet, many individuals and groups provided valuable input into the Roadmap. The roles of those who contributed varied from members of the working group, who were involved in
the development of the report, to those who took time to provide review and comments. All of these contributions are valuable and are greatly appreciated. All of the organizations and individuals worked hard to make this report a valuable resource and are proud to call it our ?commitment to the future.? It is our hope this report will be used often and will be useful in shaping the future of asphalt technology in the United States.

Strategic Plan for LTPP Data Analysis

The Strategic Objectives of the national-level analysis effort are as follows. Each Objective is important to the achievement of the overall goal. The specific Long-Term Pavement Performance (LTPP) Analysis Outcomes expected to address these Objectives are shown on the listed objective.

Strategic Objective 1 Improve traffic characterization and prediction

Strategic Objective 2 Improve materials characterization

Strategic Objective 3 Improve consideration of environmental effects in pavement design and performance prediction

Strategic Objective 4 Improve evaluation and use of pavement condition data in pavement management

Strategic Objective 5 Evaluate existing and/or develop new pavement response and performance models applicable to pavement design and performance prediction

Strategic Objective 6 Provide guidance for maintenance and rehabilitation strategy selection and performance prediction

Strategic Objective 7 Quantify the performance impact of specific design features (presence or absence of positive drainage,differing levels of pre-rehab surface preparation,etc.)
