چکیده انگلیسی
HMA's rutting characteristics and friction properties play vital roles in defining pavement structural functions and driving safety. This paper developed a novel vertically loaded wheel tester which can uniquely evaluate the rutting potential and friction resistance of eight multi-layer specimens with one experimental set-up. In this study, the rutting and friction resistance with loading cycles for four types of two-layer structures with different mixture combinations were experimentally determined. According to the results, the structures made with the AC-20 mixture as the bottom layer had significantly lower rutting depths; this infers the bottom layer properties have a more pronounced impact on the rutting resistance of the two-layer structure. For the friction resistance, the property of the top layer is more relevant the structure's friction resistance, so use of the SMA-13 mixture in the top layer is favorable. The developed test method was validated with the simulation results using the Pavement ME.
