沥青稀浆封层是用适当级配的筛屑或砂为骨料,以乳化沥青为结合料,加水,水泥(石灰)、石粉等,按一定配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,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相同。由于沥青稀浆中乳化沥青对骨料裹覆性能好、粘 Asphalt slurry seal layer is the appropriate grade with the screen scraps or sand as aggregate, emulsified asphalt as binder, add water, cement (lime), stone powder, according to a certain ratio mixing flow into the slurry state, paving Pavement made of asphalt surface treatment layer, moisture evaporation drying hardening molding, its appearance, performance, role and the same fine-grained asphalt concrete. Due to the asphalt slurry emulsified asphalt aggregate performance good, sticky
