  • Paving with asphalt emulsions - ScienceDirect

    Asphalt emulsions are water-continuous dispersions of fine asphalt droplets of 1–10 μm in diameter, manufactured with the aid of a colloid mill. The emulsions may contain between 40% and 80% asphalt by weight, and they can be anionic or cationic based on the chemical nature of emulsifiers used.

  • Chemistry of Asphalt Emulsions - Asphalt Emulsion .

    What chemicals are present in the emulsion? The main components of the emulsion are asphalt (bitumen) and water. Emulsions come in different grades but typically contain between 55 and 75% asphalt. In addition to the asphalt and water, asphalt emulsions contain 0.1-2% of an emulsifier or 'soap' which functions to stabilize the emulsion.
