tack coats. Presently, asphalt emulsions are the most used tack material throughout the world (3). However, many different grades of emulsions are used including slow set, medium set, rapid set, and quick set emulsions, high float emulsions, and polymer modified asphalt emulsions. Paving grade asphalt cements are also used for tack coats.

An Introduction to Bitumen Emulsions - Polytrade, Wood

An asphalt emulsion is mainly a stable mixture of asphalt cement, water and an emulsifying agent. Thus, this mixture has bitumen droplets suspended in water with the aid of an emulsifier. The aqueous solution can be pumped into tanks for storage, mixed with aggregates to be applied to pavement, and can be used in several different ways.

Basics of Asphalt Emulsions - Asphalt Emulsion

Asphalt emulsion is a combination of three basic ingredients, asphalt, water, and small amount of an emulsifying agent. In the same process, these components are introduced into a mechanism known as a colloid mill, which shears the asphalt into tiny droplets. The emulsifier, which is a surface-active agent, keeps the asphalt droplets in a
