Abstract:

Accelerated pavement testing (APT) has been increasingly used by state highway agencies in recent years for evaluating pavement

design and performance through applying a simulative heavy vehicular load to the pavement section under controlled fi eld conditions

in a compressed time period. However, running an APT experiment is expensive. It requires costly accelerated loading devices,

constructing full-scale pavement structures, and operator resources. It is obviously impractical to test all potential pavement structures

under APT. In order to maximize the benefi t from an APT study and utilize APT results to evaluate other pavements with similar

structural confi gurations, a fi nite element predictive model that can simulate the APT tests is an essential tool in which pavement

distress prediction functions as well as laboratory material models can be calibrated and verifi ed directly based on fi eld APT test

results.
