前言沥青稀浆封层路面,是用适当的级配筛屑(石粉),或天然河砂、人造砂等为骨料,以乳化沥青为结合料,加水、水泥等,按一定的配合比拌和成流动状态稀浆,摊铺在路面上而成的沥青表面处治层。当水分蒸发干燥硬化成型后,其外观、性能、作用与细粒式沥青混凝土路面相同。稀浆封层具有耐磨、抗滑、平整等性能;有质量好、成本低、用途广、工序简单、工程进度快的特点。是改善砂石路面、维修和养护旧沥青路面的一项新材料、新技术、新工艺。
Preface asphalt slurry seal pavement, is the appropriate grading screening crumbs (stone powder), or natural river sand, artificial sand as aggregate, emulsified asphalt binder, add water, cement, etc., according to a certain mix of mixing Into a flow of slurry, paving the pavement made of asphalt surface treatment layer. When the water evaporates and hardens dry, its appearance, performance, role and fine asphalt concrete pavement the same. Slurry seal with a wear-resistant, anti-skid, smooth and other properties; good quality, low cost, wide use, simple process, project features fast. It is a new material, new technology and new technology for improving gravel road, repairing and curing old asphalt pavement.
