摘　　要：沥青稳定碎石作为沥青路面的下层或作为柔性基层具有很多优点,是路面建设发展的一个方向,从沥青稳定碎石混合料的高温稳定性、低温抗裂性、疲劳性能进行实验分析,并用不同级配进行试验比较,以判断级配对路用性能的影响,得出对工程实际有价值的结论。The asphalt stabilized macadam, as lower surface of asphalt pavement or as flexsible base, owns a lot of merits,which is a direction of pavement develapment. From stability of asphalt stabilized macadam at high temperature, crack - resistance at low temperature and its fatigue performance, the paper does experiment and analysis of it, more over conducts testing it with different gragations in order to judge impact of gradation on road usage performance and draw a conclusions practical and valuable for project.
