Emulsified Asphalt - Pavement Interactive

Emulsions are used because they effectively reduce asphalt viscosity for lower temperature uses (tack coats, fog seals, slurry seals, bituminous surface treatments (BST), stabilization material). Emulsions are typically either anionic (asphalt droplets are negatively charged) or cationic (asphalt particles are positively charged).

An Introduction to Asphalt Emulsions | Asphalt magazine

Water is the second ingredient in an asphalt emulsion. Minerals or other materials in water can affect the production of stable emulsions. Water that is suitable for drinking may not be suitable for asphalt emulsions. The chemical used as an emulsifier greatly influences the properties of an asphalt emulsion.

Use of Asphalt Emulsions

Cationic emulsions coat damp aggregate better than anionic emulsion. Recommended use of emulsions depends on setting rate and mixing ability. At water-freezing temperatures, asphalt emulsions do not mix well since the emulsion will separate from the water.
