摘　　要：通过系统地对沥青路面抗滑性能影响因素的分析,结合室内试验对若干类型沥青混合料试件的抗滑值进行测试,并结合混合料的结构特征做了对比分析研究。沥青混合料试件包括:根据马歇尔设计方法确定最佳沥青用量的试件,比最佳沥青用量高0.5%和1.0%的试件,以及采用Superpave设计方法制作的试件和间断级配沥青混合料试件。研究发现,Superpave的抗滑值最高,之后依次是SMA和马歇尔设计方法制作的试件。By systematically analyzing the influencing factors of the antiskid performance of asphalt pavement and combining with laboratory tests, tests on the antiskid value of several types of asphalt mixture specimens are conducted and comparative researches are made by taking into consideration of the structural characteristics of mixtures. Asphalt mixture specimens include： specimens selected according to Marshall design method, specimens which have asphalt content that are 0.5% and 1.0% higher than the optimum asphalt contents, specimens that are made according to Superpave design method and gap grading asphalt mixture specimens. The research shows that the Superpave specimens rank the highest in antiskid value and then SMA and specimens made according to Marshall design method rank after.
