An Introduction to Asphalt Emulsions | Asphalt magazine

The asphalt particles are surrounded by the ionic charge, which causes the droplets to repel each other and stay suspended in the water. All asphalt emulsions are designed to eventually break, or revert to asphalt and water. Some emulsions break by chemically destabilizing the surfactant, others by a simple evaporation of the water.
