Long-Term Pavement Performance

The FHWA with the cooperation of the American Association of State Highway and Transportation Officials (AASHTO) sponsored the program.

The program was focusing on examining the deterioration of the nation’s highway and bridge infrastructure system.

The LTPP program collects data from in-service roads and analyzes it as planned by the SHRP.

It is worth to mention that the LTPP program was transferred from SHRP to FHWA in 1992 to continue the work.

The LTPP holds an annual international data analysis contest in collaboration with the ASCE.
