摘　　要：文章结合国内外对沥青路面抗滑特性的最新研究动态,分析和综述了沥青路面在长期使用过程中材料衰变所引起的微观纹理变化、宏观纹理变化以及结合料老化对沥青路面抗滑安全性的影响。研究结果表明:微观纹理决定着沥青路面的最低摩擦值,是车辆行驶安全性的基本保障,其主要在车辆低速行驶时发挥作用;宏观纹理保证了沥青路面和轮胎接触面的基本排水能力,影响着汽车雨天行驶和高速行驶的安全性,其主要在车辆雨中行驶或者高速行驶时发挥作用;结合料老化可以提高沥青路面使用初期的抗滑性能,而对后期无明显影响。Combined with the latest foreign and domestic research on asphalt pavement anti-skid property,this article analyzed and summarized the impact of micro texture changes, macro texture changes and binding-material aging of asphalt pavement caused by material decay during long-term use on the anti-skid safety of asphalt pavement.The research results showed that the micro texture determines the lowest friction value of asphalt pavement,which is the basic guarantee of vehicle driving safety,and it mainly plays its role in the low-speed driving of vehicles;the macro texture guaran- tees the basic drainage capacity of asphalt pavement and tire contact surface, affecting the safety of vehicles during the driving in rainy day or high-speed driving, it mainly plays its role when driving in rainy days or during high-speed driving;the binding-material aging can improve the anti-skid perform- ance of asphalt pavement at its early use stage and have no significant impact on its later stage.
