tack coat การใช้

• Tack coats are typically applied on adjacent pavements ( curbs ) to assist the bonding of the HMA and concrete.
• Proper repair may include first sealing cracks with crack sealant, installing paving fabric over a tack coat, or milling the damaged asphalt.
• A tack coat is a low viscosity asphalt emulsion that is used to create a bond between an existing pavement surface and new asphalt overlay.
