Asphalt Tack Coat
Asphalt tack coat is a light application of asphalt, usually asphalt emulsion diluted with water. lt is used to ensure a bond between two bituminous pavement layers and prevent slippage between layers. With a tack coat, old and new layers work together to enhance the structural performance of pavement. The goal of tack coating is to provide an even layer on the asphalt.
