The emergence of leakage problems will not only affect the quality of road and bridge construction, but also greatly reduce the use effect of the project, and seriously even threaten the lives of the people. Taking into account the negative impact of the leakage problem on all aspects, we must research and improve it as soon as possible to ensure the safety of the waterproof subgrade surface of the road and bridge. This article will carry out in-depth research and analysis on the construction technology of waterproof roadbed surface in road and bridge construction.展开更多
