摘　　要：针对沥青路面抗滑能力衰减及高速行车安全问题,调研了精表处、微表处、抛丸、罩面等四种沥青路面抗滑处治技术,分别开展了抗滑性能提升效果及抗滑性能衰减情况研究。调研结果表明:复合型高韧树脂薄层罩面技术对原沥青路面的抗滑性能提高效果最优;随着通车时间的延长,四种沥青路面抗滑处治技术的抗滑性能衰减规律是一致的。其中,复合型高韧树脂薄层罩面技术的抗滑摩擦因数衰减程度最小,持久抗滑性能最优。In view of asphalt pavement anti-skid ability attenuation and high-speed traffic safety problems,in this paper,the anti-skid treatment technology models of four kinds of asphalt pavement are established,namely,finishing surface,micro-surface,shot blasting and covering.The improvement effect and the attenuation of skid resistance were studied respectively.The results show that the composite thin layer coating technology with high toughness resin is the best to improve the anti-skid performance of the original asphalt pavement;With the extension of traffic time,the skid resistance of the four asphalt pavement anti-skid treatment technologies has the same decay law.Among them,the composite high-toughness resin thin-layer cladding technology has the least skid friction coefficient attenuation and the best lasting skid resistance.
