Road bridge pavement construction device and method thereof

The road and bridge pavement construction device comprises a mounting plate. A transmission mechanism is mounted on one side of the bottom of the mounting plate, a leveling mechanism is mounted on the other side of the bottom of the mounting plate, the leveling mechanism is connected with a fixing frame, a fan is hinged to the fixing frame, a discharging mechanism is mounted on the mounting plate, and a spraying mechanism is mounted on the side, where the discharging mechanism is mounted, of the mounting plate. By arranging the leveling mechanism, a heating roller can well extrude asphalt, so the fixing effect of the asphalt and the ground is good, the leveling and covering effects are guaranteed, and a concave-convex phenomenon is prevented; a packing auger is arranged, and asphalt is continuously stirred through the packing auger so that the asphalt is prevented from being solidified, and blockage can be avoided; by arranging the spraying mechanism, water spraying on the pavement is facilitated, so asphalt
