摘　　要：为了分析硅质石灰岩在高速公路沥青路面抗滑表层中的适用性,采用SBS改性沥青,对硅质石灰岩AC-13沥青混合料的路用性能和长期磨耗性能进行了试验研究。结果表明:AC-13硅质石灰岩沥青混合料的高稳定性、水稳定性和抗滑性能均满足规范要求;加速加载试验结果表明硅质石灰岩沥青混合料经过长期磨耗作用后,试件表面仍具有较高的摩擦系数,可以在较长的运营时间内保持较好的抗滑性能。综上,硅质石灰岩可用于高速公路沥青路面抗滑表层的建造。The pavement performance and long-term wear-resistant performance of AC-13 cherty limestone SBS modified asphalt mixture are investigated by laboratory experiments to analyze the anti-slide surface per-formance in the highway asphalt pavement. It is shown that cherty limestone could be a beneficial option for highway asphalt pavement anti-slide surface. The results of high-temperature stability,water stability and anti-sliding performance tests are subject to standards. The accelerated loading test indicates that the anti-sliding per-formance remains in good condition during the long-term operation.
