Emulsified Asphalt - Pavement Interactive

Emulsified asphalt is simply a suspension of small asphalt cement globules in water, which is assisted by an emulsifying agent (such as soap). The emulsifying agent assists by imparting an electrical charge to the surface of the asphalt cement globules so that they do not coalesce (Roberts et al., 1996 [1]).

Asphalt concrete - Wikipedia

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.
