Abstract:Based on the elastic layered theory system, the vertical additional stress distribution along the depth direction of subgrade under different driving loads of full depth asphalt structure and ordinary semi-rigid base asphalt pavement structure were analyzed in this paper. The influence of axle load level, subgrade modulus and other factors on the subgrade service depth were analyzed quantitatively. The research results show that the thicker the pavement structure thickness is, the smaller the subgrade service … Show more
