Abstract: According to the practice of G321 test road reconstruction,water had bad effects on the pavement because serious water-induced distress exists widely in traditional concrete pavements. It discusses the water diversion and water removal design of pavements to prevent the permeability of free water infiltrating into pavements,to remove rapidly the pavement surface water and the water infiltrating into pavements,and to strengthen the water-proof property of pavement structures. Based on the project practice,so...
