摘　　要：车辙的出现会严重影响行车安全,同时会缩减沥青路面的使用年限,增加后期的养护成本.改善沥青路面高温抗车辙能力以减缓车辙病害的形成是交通行业研究的重要方向.通过室内试验开展新型抗车辙DXG-1沥青路面路用性能研究,确定DXG-1的最佳掺量,同时进行SBS改性与掺DXG-1两种沥青混合料的高温抗车辙、低温抗开裂、抗水损害及抗滑能力等性能对比分析.研究表明:普通混合料高温稳定性逐渐增强;SBS改性混合料低温抗开裂及抗滑能力优于掺抗车辙剂的普通混合料;当DXG-1掺量为0.4%时,普通混合料与SBS改性混合料抗水损害能力相当.The appearance of rutting may seriously affect the driving safety,reduce the service life of asphalt pavement and increase the maintenance cost in the later stage.It is an important research direction of transportation industry to improve the high temperature anti-rutting ability of asphalt pavement to slow down the formation of rutting disease.In this paper,through indoor test,the performance of new anti-rutting DXG-1 asphalt pavement is studied,and the best content of DXG-1 is determined.The high temperature rutting resistance,low temperature cracking resistance,resistance to water damage and sliding resistance performance of SBS modified asphalt mixture and mixed DXG-1 asphalt mixture are compared and analyzed.The results show that when the content of DXG-1 increases,the high-temperature stability of ordinary mixture enhances gradually.The anti-cracking and anti-sliding ability of SBS modified asphalt mixture are better than that of ordinary mixture with anti rutting agent.When the content of DXG-1 is 0.4%,the water damage resistances of ordinary mixture and SBS modified mixture are equivalent.
