Bitumen Emulsion

Bitumen emulsions are usually two-phase systems consisting of two immiscible liquids,

bitumen and water.

Bitumen emulsions are widely used in pavement preservation techniques such as chip
seal, fog seal and micro surfacing, which look to maintain the surface properties of the

road while preserving the structural layers beneath. The types and grades of bitumen

emulsions are given in AS 1160. Proprietary emulsion binders with improved properties
are also available.
