Asphalt Emulsion - an overview ScienceDirect Topics

Asphalt emulsions are water-continuous dispersions of fine asphalt droplets, typically 1–10 μm in diameter, manufactured with the aid of a colloid mill. The emulsions may contain between 40% and 80% asphalt by weight. The emulsions have significantly lower viscosity than asphalt itself, and so can be applied at lower temperatures.
