Best Practices for Implementation of Tack Coat: Part 1

Generally, hot asphalt cement, emulsified asphalt, and cutback asphalt are used as tack coat materials. Emulsified asphalt (emulsion) includes asphalt cement and water mixed with an emulsifying agent. The emulsifying agent is added to allow water particles to exist within the asphalt cement in separate phases, since water

A method of applying building a pavement structure using a polymer modified hot-applied tack coat is disclosed. This polymer modified tack coat is non-adhesive at ambient temperatures, and, thus, also non tracking. The tack is applied while hot, but cools quickly. The subsequent application of hot mix asphalt results in a superior bond between the asphalt layer and the tack layer.

Slow-setting emulsions generally have a residual asphalt content of about 2/3. Therefore, an application rate of 0.10 to 0.15 gals/sy of the diluted material will give you the 0.03 to 0.05 gals/sy. Caution #1: Once the tack coat is applied, time must be allowed for emulsion to break (turn from brown to black) prior to placing hot mix on it. The
