2006 Symposium on Models Used to Predict Pavement Performance

WRI Pavement Performance Prediction Symposium - Models Used to Predict Pavement Performance June 2006

Western Research Institute (WRI) organized and held a Symposium on Models Used to Predict Pavement Performance, which followed the 2006 Petersen Asphalt Research Conference. The Symposium was sponsored by the Federal Highway Administration (FHWA) Turner-Fairbank Highway Research Center.

The purpose of the symposium was to hear from leading experts on the subject of models used to predict pavement performance. Presentations from the sessions and notes from a panel discussion are included below.
