Evaluation of the Loaded Wheel Tester
Predicting by laboratory testing the rutting potential of asphalt concrete mixtures has been one of the greatest challenges facing pavement engineers in recent years. It is now generally accepted that the standard mix design procedures, marshall and Hveem, do not ensure that mixtures will have a high degree of deformation resistance necessary to with stand the increasing heavy traffic loadings on our highways. A great deal of research has gone into the development of better laboratory methods to measure the resistance of asphalt mixtures to permanent deformation. This study was conducted to evaluate a new procedure to assess the rutting potential of asphalt mixes. Developed through the Georgia Department of Transportation, the procedure is based on the device which has become known as the Loaded Wheel Tester (LWT). Since the LWT is prototypical, much of this study this publication reports on was also concerned with refining the device and the procedure, and evaluating some of the testing variables.
