    An emulsion tack coat is a thin layer of bitumen emulsion applied between layers of asphalt to improve adhesion. It ensures a strong bond between the old and new layers, preventing slippage under traffic. It is applied during paving, overlays, and patch repairs to enhance the durability and structural integrity of the pavement. Proper cleaning of the surface is crucial before application.

    How thin is this coating?

    The thickness of an emulsion tack coat typically ranges from 0.1 to 0.3 gallons per square yard, which translates to a film thickness of about 0.5 to 2 mils (15 to 50 microns). This thin application is designed to create a bond without adding significant weight or thickness to the pavement structure. Proper calibration and application techniques are essential for achieving the desired coverage and effectiveness.
