摘　　要：对季冻区薄沥青面层结构交通荷载及环境适应性进行计算分析,得到薄沥青面层结构能够承担的最大交通荷载范围及适宜的气候地区;采用效益费用分析方法,与传统三层沥青面层典型结构进行对比,分析薄沥青面层结构在寿命期内的经济效益,为今后路面结构方案设计提供参考。The traffic load and environmental adaptability of the structure of the thin asphalt surface course in seasonal frozen area are calculated and analyzed,and the maximum traffic load range and suitable climate area that can be borne by the structure of the thin asphalt surface course are obtained;the economic benefits of the structure of the thin asphalt surface course in the life period are analyzed by using the analysis method of benefit cost and comparing with the typical structure of the traditional three-layer asphalt surface course,so as to provide reference for the schematic design of pavement structure in the future.
