When subgrade design and construction are unreasonable, a large amount of water will permeate downward through the pavement, which will not only destroy the integrity of the pavement, but also directly reduce the stability of the subgrade and affect the safety of the highway. In highway construction, the application of subgrade and pavement drainage construction technology should be strengthened to improve the overall drainage effect of subgrade and pavement. Therefore, in this paper, based on the background of actual engineering cases, we simply analyze and discuss the precast drainage channel technology of the expressway embankment slope for reference.展开更多
