乳化沥青是将沥青热融,经过机械的作用,以细小的微滴状态分散于含有乳化剂的水溶液中,形成水包油状的沥青乳液。 稀浆封层是一种以乳化沥青为粘结料的冷拌沥青混凝土薄层施工技术。它是将石料、沥青乳液、水泥、矿料、添加剂和水等各种配料,集中载于稀浆封层机,并通过封层机本身实现按比例连续配料拌浆和摊铺,具有和易性好,施工快捷,密实度高,粘附力强,受气候影响小,节省人力物力,无污染等优点。它对新铺筑的沥青路面,提高其平整度与搞滑性,降低路面的透水率具有很好的作用。
Emulsified asphalt is the asphalt hot melt, through the mechanical effect, in the form of fine droplets dispersed in the emulsifier-containing aqueous solution to form an oil-in-water asphalt emulsion. Slurry seal is a kind of emulsified asphalt binder for the cold-mix asphalt concrete thin-layer construction technology. It is the stone, asphalt emulsion, cement, mineral materials, additives and water and other ingredients concentrated in the slurry sealing machine, and through the sealing machine itself to achieve the proportion of continuous mixing mortar and paving, with easy Good sex, fast construction, high density, strong adhesion, small impact by the climate, saving manpower and resources, pollution-free and so on. It paved the new asphalt pavement, improve its smoothness and lubricity, reduce the permeability of the road has a good effect.
