Bitumen emulsion is usually made using a collide mill, which mixes bitumen with water and emulsifier. In this process, bitumen is milled into very small droplets that can easily suspend in the water.
With the addition of emulsifiers, bitumen droplets become more water friendly. Water droplets as well move closer to the tiny droplets of bitumen, making sure that the final bituminous product is stable enough.
In the manufacturing process, many factors such as droplets’ size, chemical addition, and the temperature of various components are accurately controlled. The resulting bitumen has a consistent structure that makes it unique for various applications.
