| 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.

| Abstract: | 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. |
