Asphalt Emulsions 101 | Asphalt magazine

An asphalt emulsion consists of three basic components, asphalt, water and an emulsifying agent. An asphalt emulsion is a stable dispersion of asphalt cement droplets in water, which can be pumped, stored and mixed with aggregates. An emulsion should “break” quickly upon contact with aggregate when mixed or after being sprayed.
