Asphalt emulsion is a combination of three basic ingredients, asphalt, water, and small amount of an emulsifying agent. In the same process, these components are introduced into a mechanism known as a colloid mill, which shears the asphalt into tiny droplets. The emulsifier, which is a surfaceactive agent, keeps the asphalt droplets in a ...
