摘要This study presents a test method to evaluate the durability of the anti-skid performance of asphalt concrete. In this work, the influence of mixture gradation, asphalt-aggregate ratio, and temperature on the texture depth is discussed for the asphalt mixture that is commonly used forth in overlays. This mixture has a nominal maximum particle size of 9.5 mm. The durability test method is used to realize the deterioration of texture depth at different wheel load times, light intensities, and water-aging damages. Experimental results show that the test method can effectively evaluate the difference in texture depths between different gradations. Texture depth is found to increase with increasing coarse aggregate content but decrease with increasing asphalt-aggregate ratio and testing temperature. Meanwhile, the residual ratio of texture depth varies with changing laws and under different aging conditions and wheel load times.
