摘　　要：半柔性复合路面可用于解决交叉口重载交通引起的车辙问题。为了研究半柔性沥青混合料的路用性能,以SMA-13沥青玛蹄脂碎石混合料为对比材料,分析二者的水稳定性能和高温、低温性能的差异。结果表明:半柔性沥青混合料的水稳定性和高温性能均优于SMA-13混合料,低温抗裂性能和抗疲劳性能稍逊于SMA-13混合料,但可以满足规范要求。Semi-flexible composite pavement can be used to solve the rutting problem caused by heavy traffic at intersections.In order to study the road performance of semi-flexible asphalt mixture,stone matrix asphalt SMA-13 is taken as the contrast material to analyze the difference of water stability,high temperature performance and low temperature performance between them.The results show that the water stability and high temperature performance of the semi-flexible mixture are better than that of SMA-13,the low temperature crack resistance and fatigue resistance are slightly lower than SMA-13,but can meet the requirements of the code.
