- Abstract:
-
The mechanical elleets of rellective eracking prevention on rubber powder modilied asphalt stressabsorbing layer is caleulated and analyzed by ANSYS modeling. Then the stress elfeets of the various interlayerparameters are also diseussed. The results show that the stress absorbing layer of rubber modilfied asphalt canelleelively prevent relleelive eracking of asphalt layers paved on the old cement pavement, the stress conditionof the surfaee layer can be improved significantly by redueing modulus of the sress absorbing layer, and therelleetive eraeking could be redueed correspondingly. The author reeommends the reasonable modulus range ofthe rubber powder modified asphalt stress absorbing layer is 50 Mpa ~200 Mpa, and the reasonable thicknessis 0.5 cm~2.5 cm.
