TRB’s Long-Term Pavement Performance (LTPP) Committee has released a report that presents a recommendation for the safekeeping, management, and operation of the LTPP database for decades to come. The LTTP Committee advises the Federal Highway Administration and the American Association of State Highway and Transportation Officials on the planning and execution of the LTPP studies. The LTPP studies are a set of operational activities consisting of gathering and analyzing data that is being collected on more than 2500 in-service pavements in the United States and Canada. The principal objective of this data collection and analysis is to further the understanding of how and why pavements deteriorate when subjected to traffic loadings and environmental conditions.
