摘　　要：为了研究路面抗滑性能测试方法的适用性,有效地评价沥青路面抗滑性能,结合实体路段检测,采用横向力系数测试方法和激光构造深度测试方法分别进行测试,比较两种方法的适用性和优劣;通过研究成果调查及实体道路测试数据分析,对横向力系数和构造深度的相关性进行了探讨。结果表明:横向力系数和构造深度均可以准确地评价路面抗滑性能,但应用范围有所差异;两者在特定条件下具有一定的相关性。In order to study the suitability of the test methods for skid resistance of pavement and make effective evaluation,the investigation on road section was conducted by measuring sideway-force coefficient and texture depth respectively,and the pros and cons of each test method were pointed out.The correlation between sideway-force coefficient and texture depth was discussed based on the indoor test and the measured data.The results show that despite the difference in the range of application,both the sideway-force coefficient and texture depth can accurately evaluate the skid resistance performance of pavement;there is no significant correlation between the two,which merely shows under particular conditions.
