国外沥青路面抗滑性能影响因素研究

Study on Factors Influencing Skid Resistance of Asphalt Pavement Abroad

从轮胎与沥青路面间接触机理、沥青路面抗滑性能的评价方法和沥青路面抗滑性能的衰减规律三个方面,对国外的研究成果进行归纳总结。沥青混合料的材料特性和结构特性对沥青路面的抗滑性能影响较大,路表宏观纹理和微观纹理共同作用影响路面的抗滑性能,以优质石料作骨料的骨架嵌挤型沥青混合料结构表现出良好的抗滑性能。

This paper summarizes the foreign study achievements from three aspects of the contacting mechanism between tire and asphalt pavement, the evaluation method of asphalt pavement skid resistance and the attenuation law of asphalt pavement skid resistance. The material characteristics and structural properties of asphalt mixture have the great influence on the skid resistance of asphalt pavement. The combined action of macroscopic texture and microcosmic texture on the road surface will influence the skid resistance of pavement. The skeleton extruded asphalt mixture structure using the high-quality building stones as the aggregate has the good skid resistance.
