Asphalt Emulsions 101 | Asphalt magazine

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. Breaking is the separation of the water from the asphalt.

Asphalt Emulsion - an overview | ScienceDirect Topics

Asphalt emulsion (emulsified asphalt), like cutback asphalt, is also designated as a liquid asphalt to distinguish this product from the typical semisolid to solid asphalt binders. It is a mixture of two normally immiscible components (asphalt and water) and an emulsifying agent (usually soap).

Emulsified Asphalt - Pavement Interactive

Generally, emulsions appear as a thick brown liquid when initially applied (Figure 1). When the asphalt cement starts to adhere to the surrounding material ( aggregate, existing surface, subgrade, etc.) the color changes from brown to black (Figure 2) and the emulsion is said to have “broken” (Figure 3).
