Research on Mechanical Response Characteristics of Asphalt Pavement Structure Based on ADINA
In order to study the mechanical response characteristics of asphalt pavement structure layer under saline soil subgrade with different grades and different improvement depths on Xiongan-huanghua Expressway,this paper adopts the methods of similar scale and simulation model calculation to analyze the stress and displacement of asphalt pavement structure layer.The research shows that the highway grades are different,but the changes of section stress and Z-direction displacement will remain consistent;the higher the highway grade is,the smaller the stress fluctuation and displacement change of the asphalt structure layer are.The improvement depth of saline soil subgrade has little influence on the change of stress response.
