Asphalt Emulsions

Asphalt emulsions are manufactured by milling asphalt cement (bitumen) into microscopic particles and dispersing them in water using a chemical emulsifier. The tiny droplets of asphalt remain uniformly suspended until the emulsion is used.

The chemistry of the asphalt emulsion determines the stability of the system. When emulsions are used in the field, the system will at one point become unstable and cause the asphalt and water suspension to shift. This causes the water to evaporate, leaving behind residual asphalt that coats and bonds to aggregates when used during a road application.

McAsphalt’s asphalt emulsions have a wide variety of applications, from tile adhesives to vehicle undercoating. The primary uses are tailored toward roads, including seal coating, recycling and slurry systems.

Anionic Emulsions

Chemical surface-active agents, which serve as emulsifiers, are classified by the electrochemical charge that is attained when they dissociate in a water solution. In the case of anionic emulsions, the chemical charge is negative.

Cationic Emulsions

Chemical surface-active agents, which serve as emulsifiers, are classified by the electrochemical charge that is attained when they dissociate in a water solution. In the case of cationic emulsions, the chemical charge is positive.
