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 con-trast 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 bet-ter 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.
