摘　　要：从重载条件下的车辆轴载特性分析入手,选取合理的荷载作用计算图式,着重研究重载交通条件下沥青面层内的应力分布水平,分析路面车辙的产生机理及重载条件对车辙深度的影响,并应用车辙预估模型对比不同层位抗车辙改良效果,为设计、施工提供一定的理论支撑。Starting with the analysis of vehicle axle load characteristics under heavy load,the reasonable diagram of load action calculation is selected,the stress distribution level in asphalt pavement under heavy load traffic conditions is specially studied,and the generation mechanism of pavement rut and the influence of heavy load condition on rutting depth are analyzed,and the effects of anti-rutting improvement in different layers are compared by the rutting prediction model,which provides certain theoretical support for the design and construction.
