Understanding Your Emulsions - Bergkamp Inc.

Many factors can contribute to emulsion breaking prior to use on the road surface, but when an emulsion breaks, the asphalt component bonds to the nearest surfaces. In pavement preservation, the break needs to occur after the application of the emulsion to ensure a strong chemical bond with the road surface and aggregate.
