摘　　要：为了评估稀浆封层沥青路面的路用性能,文章采用90#基质沥青和SBR改性剂,通过动稳定度、抗弯拉强度、渗水系数、粘结强度和抗滑摆值等试验,系统分析了稀浆封层及其改性剂的性能表现,研究结果表明,稀浆封层能够提高沥青路面的高温稳定性、低温抗裂性和防水性能,尤其是SBR改性剂的掺入,进一步增强了沥青混合料的路用性能,尤其在高温和低温条件下表现突出,尽管抗滑摆值有所下降,但仍满足规范要求,显示出较好的路用性能。In order to evaluate the road performance of slurry seal asphalt pavement,90#base asphalt and SBR modifier were used to systematically analyze the performance of slurry seal and its modifier by dynamic stability,flexural tensile strength,water permeability coefficient,bond strength and anti-sliding pendulum value.The results show that slurry seal can improve the high temperature stability,low temperature crack resistance and waterproof performance of asphalt pavement.Especially,the addition of SBR modifier further enhances the road performance of asphalt mixture,especially under high temperature and low temperature conditions.Although the anti-sliding pendulum value has decreased,it still meets the requirements of the specification.It shows good road performance.
