Products derived from the Long-Term Pavement Performance (LTPP) program have been made available to State departments of transportation and other segments of the highway community since the early years of the program. Initially, these were methods, guidelines, and procedures for standardized testing and performance data collection. While these procedures were developed to meet LTPP data-collection needs, their conversion into standard practices has been an American Association of State Highway and Transportation Officials (AASHTO) activity. Some products and benefits from LTPP already implemented in practice are based on best-practice construction specifications developed for the pavement experiments requiring new construction, while other products were developed from early analysis of LTPP data.
Throughout the life of the LTPP program, significant efforts have been made to improve data accessibility for all potential users. At least once a year for more than a decade, standard data releases containing data from the LTPP database have been made available on DVDs, USB drives, and more recently, the Internet.
