人们为了改善加热沥青的施工条件,从本世纪初就开始探索研究乳化沥青,开始曾用粘土或牛血做为乳化剂,至1925年应用肥皂做乳化剂,并在欧洲开始沥青乳液的商品化生产。由于这种沥青乳液具有良好的流动性,在常温状态下,不需加热即可直接用于施工,可以均匀地分布在工程(或材料)的表面上,操作方便,节省沥青的用量,施工现场不需支锅熬油,工人们避免了烟熏火烤和沥青蒸气中毒,也防止因用热沥青而引起的烧伤,烫伤及火灾等安全事故的发生,因之乳化沥青技术得到普及与推广,1928年传
In order to improve the construction conditions for heating asphalt, people started to explore emulsified asphalt from the beginning of this century and began to use clay or bovine blood as emulsifier. Soap was used as an emulsifier in 1925 and the commercialization of asphalt emulsion began in Europe produce. Because of this asphalt emulsion has good fluidity, at room temperature, without heating can be used directly for construction, can be evenly distributed in the engineering (or material) surface, easy operation, saving the amount of asphalt, the construction site No boil oil boil, the workers to avoid the smoke fire roasted and bituminous vapor poisoning, but also to prevent the use of hot asphalt caused by burns, scalds and fire and other safety incidents, because the emulsified asphalt technology has been popularized and promoted, 1928 Biography
