摘　　要：沥青路面车辙产生的主要原因是沥青混合料抗剪强度不足所致,仅依赖改性沥青的粗型密级配沥青面层将无法满足路面抗车辙要求。在沥青混合料中掺加各种外加剂后,对其动稳定度进行比较、分析,表明该方法是提高沥青混合料路用性能的有效途径。The main reason of rutting in asphalt pavement is that asphalt mixture is lack of shear strength. The modified asphalt coarse-dense distribution asphalt pavement will not be able to meet the requirements of the road anti-rutting. On this basis, after adding various admixtures into the asphalt mixture, comparison and analysis of its dynamic stability showed that mixing various admixtures can effectively improve the performance of asphalt pavement.
