Asphalt Emulsion - an overview ScienceDirect Topics

James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 1.2.1.4 Asphalt Emulsion. 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).

Asphalt - an overview ScienceDirect Topics

Here, the asphalt emulsion modified with BUTONAL® NS198 was mixed with Portland cement to create an asphalt binder for the microsurfacing. The emulsion does not break, but rather becomes viscous after 1 -2 minutes of mixing, resembling the mixing (open) time of the entire microsurfacing formulation.

8.2.1 Asphalt Emulsion. Asphalt may also be emulsified to produce a liquid product that can be pumped and transported by pipeline, mixed with aggregate, or sprayed through nozzles. Emulsified asphalts consist of minute globules of asphalt (generally in the colloidal size range) suspended in chemically treated water.
