Research on Effect of Roadbed Flooding on Sinkage of Permeable Pavement
In order to explore the sinkage behavior of the pavement and subgrade caused by the softening of the permeable pavement roadbed,the EDEM software is used to analyze the sinkage of each layer.The simulation results show that the roadbed soil after flooded,the upper permeable gravel will be inlaid into the roadbed soil under the action of vehicle load,which makes the pavement large sinkage,and the sinkage amount is almost generated by the gravel base and roadbed soil layer.
