Emulsified asphalt equipment improves the fluidity of asphalt: When the emulsified asphalt equipment is subjected to mechanical actions such as high-speed centrifugation, shearing, and impact, the emulsified asphalt equipment makes it into particles with a particle size of 0.1~5μm, and disperses it into a water medium containing a surfactant (emulsifier-stabilizer).由于乳化剂可以在乳化沥青设备颗粒的表面上定向吸附，因此降低了水和沥青之间的界面张力，因此沥青颗粒可以在水中形成稳定的分散系统。乳化的沥青设备是一种水中乳化。
