摘　　要：我国城镇道路中沥青路面的车辙现象比较严重,在沥青路面的车辙计算上,《城镇道路路面设计规范》和《公路沥青路面设计规范》采用了不同的计算方法及分析标准。通过对两种计算方法的适用情况、范围以及计算结果对比分析,总结出两种计算方法的不同及各自的优缺点,《公路沥青路面设计规范》的计算方法考虑的因素更加全面,但对于城镇道路的公交车站及交叉口处的频繁启动及制动路段的情况分析不足,城镇道路应在《公路沥青路面设计规范》计算方法的基础上对频繁启动及制动的特殊路段进行研究及完善。The rutting phenomenon of asphalt pavement in urban roads in China is relatively serious.In the rutting calculation of asphalt pavement,different calculation methods and analysis standards are adopted in the Code for Design of Urban Road Pavements and the Code for Design of Highway Asphalt Pavements.Through the comparison and analysis of the applicability,scope and calculation results of the two calculation methods.The differences and advantages and disadvantages of the two calculation methods are summarized,the calculation method of the Code for Design of Highway Asphalt Pavements is more comprehensive,but the analysis of the frequent starting and braking sections at the bus stops and intersections of urban roads is insufficient.Urban roads should study and improve the special sections of frequent starting and braking on the basis of the calculation method of the Code for Design of Highway Asphalt Pavements.
