In order to strengthen the bonding between the asphalt layer of the pavement and the asphalt layer, cement concrete panel, and asphalt-stabilized gravel base, the thin asphalt layer is sprinkled; Yes: Make the upper and lower layers of asphalt structure, or the asphalt structure layer and the structure, completely bonded into a whole;
Sealing layer: It is to close the surface gap and prevent moisture from intruding into the surface layer and the base layer. The thin layer of asphalt mixture paved on the surface layer is called the upper seal layer, and the lower layer is called the lower seal layer. The function is: upper The sealing layer is laid on the asphalt concrete surface to seal the water and resist the wear of the wheels.
