随着交通量的大幅增大,极端天气的出现,行车荷载的加重使车辙病害更加突出,缩短了沥青路面使用寿命。我国现行规范中评价沥青混合料的高温抗车辙的能力指标为动稳定度,本次针对AC-20沥青混合料动稳定度进行有关的试验分析。
With the dramatic increase of traffic volume, the occurrence of extreme weather and driving load aggravate the rutting diseases and shorten the service life of asphalt pavement. China’s current norms to assess the high temperature rutting resistance of asphalt mixture as a dynamic indicator of stability, the dynamic stability of AC-20 asphalt mixture for the relevant test analysis.
