Evaluation of Rutting Resistance of Double-layered Asphalt Mixes
The wheel tracking test is one of the important methods to evaluate the high-temperature performance of asphalt mixes. In this paper, the rutting resistance of composite structures of surface/intermediate layers was studied by using both the Circular Road Track (CRT) test and the Hamburg Wheel Tracking Device (HWTD). Several performance indices, including the dynamic stability, rut depth, and deformation profiles, were evaluated and compared to determine the rutting resistance of several double-layered asphalt mixes. Several approaches to mitigate rutting in asphalt pavements were suggested by this study, such as use of modified binders in the intermediate layer, and addition of polyester fibers into Stone Mastic Asphalt (SMA). The HWTD test has the potential to replace existing Chinese wheel tracking test as a routine test procedure for determining the rutting resistance of asphalt mixes.
