Cement concrete engineering way of surface treatment and relevant demands and engineering characteristics, so according to the requirements of engineering, the equipment and construction technology are also different. Bridge deck chisel deck chisel MAO MAO's main purpose is to solve the problem of interlayer bonding. The floating slurry of cement concrete bridge deck is induced by bridge deck waterproof layer failure, interlayer combination of damage and the main factors of bridge deck pavement damage. Hew as a result, if not completely bridge deck laitance, bleeding in vibration under the action of traffic load, the interlaminar stripping due to shear capacity, and under the erosion of water burst, lead to the upper layer asphalt concrete destruction.
