摘要
沥青路面封层技术可用于路面预防性养护、中修、层间应力吸收层、桥面铺装防水层,在一定程度上改善路面表观性能,封闭路面裂缝,阻止水分下渗。辽宁省应用封层技术较早,应用效果也较好,就辽宁省常用的封层技术特点、工艺要求、适应性、工程应用等进行综合说明。
Seal coat technology of asphalt pavement can be used in preventive pavement maintenance, repair, interlayer stress absorbing layer, waterproof layer of bridge deck pavement. To some extent, the tech- nology can improve pavement apparent performance, close the road surface crack, and prevent water infiltra- tion. Seal coat technology has been applied for years in Liaoning province, and has a good effect. This paper comprehensively discusses the characteristics of commonly used seal coat technology, technical requirements, applicability, and engineering application in Liaoning province.
