摘　　要：沥青混凝土路面的车辙问题主要源于车辆交通繁忙、夏季高温以及春季路基土壤水分增加等因素。此外,路面或基层的抗剪力不足,以及路基核心区的土壤也会导致车辙的形成。同时,路面上层的磨损、压实过度或破坏以及剥落等问题也会对路面层造成影响。因此,为了解决这些问题,需要采取相应的措施提高路面的抗剪能力和稳定性。从沥青路面抗车辙技术措施角度出发,对路面计算的设计解决方案进行了分析和研究,确定了车辙的参数,评估了路面在轨道深度方面的运行条件,并分析了路面沥青混凝土的物理和机械性能,从而进一步提高沥青路面的抗车辙能力。Rutting of asphalt concrete pavements is mainly caused by heavy vehicle traffic,high temperatures in summer,more soil moisture in subgrades in spring and other factors.In addition,insufficient shear resistance of pavements or bases and soil in the core areas of subgrades will lead to rutting.Meanwhile,wear,excessive compaction,damage and peeling of the upper layers will affect pavements.In order to solve these problems,appropriate measures should be taken for higher shear resistance and stability of pavements.From the perspective of technical measures against rutting of asphalt pavements,the design solution for pavement calculations was analyzed and studied,rutting parameters were determined,the operating conditions of pavements in terms of track depth were evaluated,and the physical and mechanical properties of asphalt concrete pavements were analyzed,thereby further improving the rutting resistance of asphalt pavements.
