Long-Term Pavement Performance (LTPP) program continued to work toward these goals
through its efforts to provide answers to “how” and “why” pavements perform as they do.
To better understand pavement performance, the LTPP program gathers and processes data
describing the structure, service conditions, and performance of more than 2,400 pavement
test sections in North America. Highway engineers can use these data and findings from the
analyses conducted to date to help them make decisions leading to more cost-effective and
