| Abstract: | Considering the friction contact condition of asphalt surface and semi-rigid base,the change law of the stress intensity factor of asphalt pavement surface crack was analyzed under moving vehicle load.The effect of different surface thick-ness,surface modulus, base modulus and different crack depth was studied.Some theoretical reference was provided for improving the design method of asphalt pavement for resisting crack and for the maintenance and rehabilitation of asphalt pavement. |
