what is asphalt emulsion
Asphalt Emulsions. Asphalt emulsion is a combination of three basic ingredients; asphalt, water, and small amounts of 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.sphalt emulsions are used in cold processes for road construction and maintenance. Emulsions are classified on the basis of how quickly the asphalt droplets will re-coalesce (break and setup). The terms rapid set (RS), medium set (MS), quick set (QS) and slow set (SS) have been adopted to classify the emulsions.
