摘　　要：采用单轮式横向力系数测试仪对不同路表材料的9段高速公路(分别为AC-13的4段、AC-16的3段、Superpave-13的2段),每隔半年进行1次抗滑性能跟踪检测,分析抗滑性能与通车时间、累计轴载作用次数的关系,比较抗滑性能在累计轴载作用次数、沥青混合料级配、粗集料磨光值(PSV)等多因素耦合作用下的衰变规律,给出AC-13、AC-16、Superpave-13路面抗滑性能衰变规律预测模型。The Anti-silding Performance of 9 sections of expressways with different road surface materials(respectively AC-13 section 4,AC-16 section 3,and Superpave-13 section 2)is tracked and tested once every six months by using a single wheel lateral force coefficient tester,so as to analyze the relationship between the Anti-silding Performance and the opening time and the cumulative axle load action times,and compare the decay law of the Anti-silding Performance under the multifactor coupling effect like the cumulative axle load action times,the asphalt mixture gradation,the polished value(PSV)of coarse aggregate and so on,and the decay law prediction model of the Anti-silding Performance of the pavement like AC-13,AC-16,and Superpave-13 is given.
