Abstract
The Wheel Tracking Test (WTT) is already established as a standard test method to evaluate the plastic deformation resistance of the asphalt mixture and its effectiveness has been generally accepted, in Japan. Obtained data from recoverable deformation measurement using the WTT will provide very useful information for the permanent deformation predication of the asphalt mixture.
In this paper, a measurement method of recoverable deformation behavior using the WTT is described and obtained data of several asphalt mixtures are shown. Next, a permanent deformation analysis method based on stiffness of binder and the mixture shown in “Standard specification for pavenents-2007” is applied to these obtained data. The calculated results are compared with the measured results. Then, compatibility and issues on the analysis model are described.
