Expected Service Life of Hot-Mix Asphalt Pavements in Long-Term Pavement Performance Program

Abstract

One of the objectives for the Long-Term Pavement Performance (LTPP) program is to develop improved design methodologies for pavements. To achieve that objective, hundreds of hot-mix asphalt (HMA) test sections have been established and are being monitored to determine the performance characteristics of HMA pavements. The data from this program can be used to validate improved design methodologies and to establish the service life of HMA pavements. Specific findings are summarized from a study sponsored by the Asphalt Pavement Alliance to determine the expected service life of HMA or flexible pavements included in LTPP by using survivability analyses.
