摘要

Abstract

Based on unsaturated seepage theory,this paper proposes a new type of pavement drainage system,which is based on the use of geocomposite materials as drainage channel.From the top to the bottom part of the new drainage system is transport layer,capillary barrier layer and isolation layer.In this paper,the author uses unsaturated seepage theory to research the performance of new pavement drainage system.The model test is carried out.Comparing with the new drainage system and the traditional drainage method,model test monitors the pavement structure layer drainage volume and matrixsuction.Model test result shows that the new drainage system can start draining when the base was in unsaturated state.The drainage capacity of the new drainage system is 1.25 times than the traditional drainage,and the new drainage system can be more rapid drainage,which can reduce the internal moisture of the pavement base layer and improve its bearing capacity.
