在世界各地的公路发展中,欧洲的公路是先进的和发达的,路面的铺装率大部分已达90～95％以上,公路的密度已达1.4～1.8km/km~2以上,热沥青混合料的生产设备十分普遍,但是,这些情况不仅没有影响欧洲乳化沥青的发展,而且,欧洲应用乳化沥青很普遍,技术上也很先进。据文献记载, In the development of roads around the world, the roads in Europe are advanced and developed. The pavement rate of most pavement has reached 90-95%, the density of roads has reached 1.4 ~ 1.8km / km ~ 2, and hot asphalt Mixture production equipment is very common, however, these conditions not only did not affect the development of emulsified asphalt in Europe, but also the application of emulsified asphalt in Europe is very common and technically advanced. According to the literature,
