摘　　要：结合工程实例,按照"强基薄面"建设理论,采用路面结构设计程序HPDS对沥青混凝土单面层和双面层进行了弯沉和弯拉应力计算和分析,运用弹性层状理论对沥青路面单面层与双面层结构进行了力学计算和分析。实践证明,在基层厚度和强度足够的情况下,单面层沥青路面在中小交通量公路项目中较双层沥青路面具有一定的优势,这些分析和探讨对以后实施类似工程有一定的参考和借鉴意义。Combining with the engineering example,according to the construction theory of"strong foundation and thin surface",the program design of pavement structure HPDS the deflection and bending stress calculation and analysis of asphalt concrete single layer and double layer,using the elastic layered theory of mechanics calculation and analysis of asphalt pavement with single layer and double layer structure. In practice,the thickness and strength enough,a single layer of asphalt pavement with double-layer asphalt pavement has certain advantages in small and medium-sized traffic highway project,the analysis and discussion of the implementation has certain reference significance for similar engineering in the future.
