2004 Symposium on Prediction of Pavement Performance "Additives Used in Asphalt Pavements"

Western Research Institute (WRI) held a Symposium on Additives Used in Asphalt Pavements in cooperation with 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 the values of various additives used in asphalt pavements. There were four half-day sessions. Presentations from the sessions are included below.
