The Long-Term Pavement Performance (LTPP) program is a 20-year study of inservice pavements across North America. Its goal is to extend the life of highway pavements through various designs of new and rehabilitated pavement structures, using different materials and under different loads, environments, subgrade soil and maintenance practices. LTPP was established under the Strategic Highway Research Program (SHRP), and is now managed by the Federal Highway Adminstration (FHWA).
