Analysis of Displacement Filed of Asphalt Airport Pavement

Considering the future development trend of the airport pavement, a 3-D finite element model with 45m×20m×11.62m full-scale slabs is established to analyze the displacement response of asphalt concrete airport pavement under aircraft loads. Under different aircraft tire pressure levels, the vertical displacement and vertical displacement curve of the pavement in the region between 9 m and 13 m outside aircraft wheels is analyzed. The mechanical response of flexible pavement is studied, and the influence of various parameters on asphalt pavement.
