The Chemistry of Asphalt Emulsions

Asphalt emulsions, used in road construction and maintenance, may be defined as an homogeneous mixture of minute asphalt droplets suspended in a continuous water phase. These types of emulsions are usually termed oil-in-water (o/w) emulsions. Their preparation involves the use of a high speed, high shear mechanical device, such as a colloid mill. The colloid mill breaks down molten asphalt ...

Overview of Asphalt Emulsions Semantic Scholar

The use of asphalt emulsions began in the early part of the 20th century. Today 5% to 10% of paving-grade asphalt is used in emulsified form, but the extent of emulsion usage varies widely between countries. The United States is the world's largest producer of asphalt emulsion. The advantages of asphalt emulsion compared to hot asphalt and cut back binders are related to the low application ...
