一、乳化沥青的发展趋向乳化沥青的发展已有五十多年历史。所谓乳化沥青就是将微小的沥青颗粒稳定地均匀分散于水中,成为水包油型的乳浊液,使它在常温状态下,能够成为可以铺筑路面或是建筑防水用的流动乳液,这就大大改善了施工条件。首先,在施工现场不需要将沥青加热熬制到一定高温才能使用,这就节省很多的燃料与热能,根据国外调查,铺一平方米2.5厘米厚的热沥青混凝土路面,需要8,379仟卡热能,而铺同样数量的乳化沥青
First, the development of emulsified asphalt Emulsified asphalt development has more than 50 years of history. The so-called emulsified asphalt is the tiny asphalt particles stably dispersed evenly in the water, as oil-in-water emulsion, so that it can be at room temperature can be paved road or building waterproof with the flow of emulsion, which Greatly improved construction conditions. First of all, it is not necessary to heat the asphalt to a certain high temperature to be used at the construction site, which saves a lot of fuel and heat. According to the survey conducted abroad, laying a 2.5-centimeter-thick hot asphalt concrete pavement requires 8,379 kilocalories, Shop the same amount of emulsified asphalt
