Title: Predicting in-service pavement performance from accelerated testing
Abstract: When the National Center for Asphalt Technology decided to build a pavement test track, the Indiana Department of Transportation saw an opportunity to establish rutting performance relationships between the Accelerated Pavement Tester, the Purdue Wheel Tracker, and the in-service pavement as represented by the test track. It participated in the test track pooled fund study by sponsoring two pavement sections that were part of a larger investigation involving ten pavement test sections. Direct comparisons between the accelerated test methods were made; finite element modeling techniques were also used to model in-service rutting using accelerated testing results. The research indicates that while direct comparison of accelerated testing and in-service performance may be possible, the finite element modeling may be more capable of relating the accelerated and in-service rutting results.
