Abstract:The goal of the ongoing, 20-year long-term pavement performance (LTPP) studies is to give State and Provincial transportation departments- the owners and customers of the LTPP program-the information and tools they need to build and maintain longer-lasting pavements. The Roadmap charts a course to the program's near-term and longer term destinations, which are based on the products needed by State and Provincial highway agencies today. The Roadmap was developed with input from all of the partners, which include State and Provincial highway agencies, the American Association of State Highway and Transportation Officials (AASHTO), the Transportation Research Board, industry, academia, and FHWA. The LTPP program is a dynamic process; as needs and priorities shift, the Roadmap and data analysis plan will be adjusted accordingly. The LTPP products are aimed at improving the selection and effectiveness of pavement maintenance strategies, the performance of various pavement rehabilitation techniques and materials, and the selection of design features for new construction or reconstruction of pavements. Some products are already available, including those related to materials testing, pavement performance monitoring, and equipment standards and calibration procedures. Still under development are products directed at the selection and effectiveness of maintenance strategies, performance of various rehabilitation techniques and materials, and the selection of design features for new or total reconstruction. The LTPP data analysis plan contained in the Roadmap outlines how the data being collected can best be analyzed and applied to achieve the LTPP objectives. The partners in the LTPP program will develop detailed plans for conducting the studies, analyzing the data, and reviewing the results. The LTPP data analysis will augment the work being done by the AASHTO Joint Task Force on Pavements.
