摘要: 本文就沥青路面罩面工程实践,提出了采用乳化沥青稀浆封层作沥青路面的下封层,它既可增强路面的防水功能,又可提高新铺罩面与旧路面的层间结合,还可省去旧路面拉毛等工序。根据试验进行了稀浆封层的配合比组成设计,在实际工程中取得了很好的路用技术效果。

The application research on emulsified bitumen slurry seal as under seal in bituminous mixture overlay
CUI Wu-cheng
Abstract : According to the practices of bituminous mixture overlay engineering, the article introduce a way by using emulsified bitumen slurry seal as under seal in asphalt overlay. Three virtues can be found, enhancing waterproof performance of the pavement, reinforcing the combinative ability between the new spreading cover and the old road, avoiding making coarse to old pavement. Mixture proportion design of emulsified bitumen slurry seal is done based on experiments and good effect is achieved in practice
