2005 Prediction of Pavement Performance Symposium - Adhesion and Cohesion in Asphalt Pavements
Western Research Institute
(WRI) held a Symposium on Adhesion and Cohesion 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 adhesion and cohesion in asphalt
pavements. There were four half-day sessions. Presentations from the sessions
are included below.
