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.

Why is it called fog seal?

Why is it called fog seal?

A fog seal is an application of a specially formulated asphalt emulsion (a thin liquid oil) to an existing asphalt pavement surface. A fog seal gets its name from its spray application, sometimes referred to as “fogging.”

How long does fog seal take to dry?
