Mechanical Analysis on Asphalt Mixture Overlaying on Old Cement Pavement Disengaged in the Corner
Based on the theory of elastic layer system,calculation models of asphalt overlaying on old cement pavement structure were established.According to finite element software,in allusion to a hollow under a slabs edge or its comer,series of key factors to stress and deflection of asphalt overlay have been studied,which includes cooling rate,axle load,and cement concrete slab thickness.In light of the calculation results,the development rules of stress and displacement were summarized.The relations between asphalt overlay equivalent stress,maximum shear stress,deflection and the influence factors were obtained,respectively.
