- Abstract:
- The usage limit of road decreases with the appearance of asphalt pavement early crack．In order tostudy the propagation behavior of asphalt pavement surface crack in use，the change law of the stress intensityfactor Kll of surface crack was analyzed under moving load with the commerce FEM software ABAQUS basedon fracture mechanics theory．The response of asphalt pavement with surface crack was studied under the con．dition of different crack depth and different frictional contact status between layers．The effects of pavementparameters such as surface thickness and surface modulus and base modulus on the crack propagation were dis—cussed．Some theoretical reference was provided for the rational design of semi—-rigid asphalt pavement andfor the maintenance and rehabilitation of asphalt pavement．
