DIGGING INTO LTPP PAVEMENT DATA

The Long-Term Pavement Performance (LTPP) database represents the largest collection of pavement performance data ever compiled, containing nearly 2 decades of data on climate, materials tests, maintenance, rehabilitation, traffic, and pavement monitoring. To encourage greater use of the LTPP data to benefit the pavement industry, the Federal Highway Administration (FHWA) challenged students and faculty from the U.S. and around the world to come up with new, innovative analyses of the LTPP data. This article provides an overview of 5 separate research papers that were generated by academic participation in the LTPP/FHWA project.
