Design of road infiltration based on infiltration coefficient of pavement

Based on the analysis of the criterion of road infiltration,it was the pavement infiltration on some damage condition which affected the road infiltration.Therefore,through the analysis of the theory of permeable pavement based on permeable base layer,the design model of road infiltration was established.The parameter of the model was calibrated by the test data,and the method to calculate road infiltration was then determined.
