主　　题：small stone asphalt mixture mixture design anti-skidding performance attenuation of skid resistance 

摘      要：Small stone asphalt mixture（SSAM） was designed by Bailey method and coarse aggregate voids-filling *** optimum asphalt content was determined by Marshal *** texture depth for SSAM with different voidage,and the BPN of SSAM and SMA before after wet track abrasion were *** experimental results indicate that the surface texture depth increases with the decreasing of asphalt aggregate *** SSAM with the optimal asphalt content has a good skid *** of asphalt mixture decreases with the increasing of wearing time,but the extent of reduction is *** reduction rate of BPN for SSAM is smaller than that of SMA,indicating that SSAM has a good skid resistance attenuation ***,the other properties of SSAM are also evaluated,showing that the splitting strength and modulus and SSAM are higher than those of SMA,and the other properties of SSAM,such as high-temperature performance and water stability can also satisfy the technical requirements.
