Abstract
Asphalt pavement life is typically a function of traffic volume and environment condition. Asphalt pavement gradually deteriorates over its service life. This study focuses on the long-term performance monitoring of asphalt pavement by rutting measurement and embedded instrumentation. Results of this study indicated that strains increased with the number of equivalent single-axle load (ESALs). Rut depth also increased with strains. Rate of increasing strains was considerably high at the beginning but gradually decreased with ESALs. The increase in the measured rut depth was consistent with the increase in permanent deformation obtained from embedded instrumentation. Finally, the study suggested that the measured strains from embedded instrumentation could be estimated the long-term rutting of asphalt pavement.
