In order to study the adaptability of reasonable pavement structure in permafrost regions, the first-stage construction of Gonghe-Yushu highway from K629 + 800 ~ K634 + 200 is taken as test section, and establishes the numerical simulation model of subgrade and pavement by using Flac3D software. Compares and analyzes the mechanical properties with semi-rigid base asphalt pavement and flexible base asphalt pavement structure. In the end, recommends a reasonable pavement structure type in permafrost regions: flexible base asphalt pavement structure. The results show that: in the long term, the deformation range of flexible pavement structure is less than the semi-rigid base pavement structure. Therefore, the permafrost region pavement structure should give priority to the flexible base asphalt pavement structure.
