When it is necessary to pave the road with asphalt, asphalt is added to the material storage box, then the first motor and the second motor are started to stir the asphalt, and then the asphalt flows out through the discharging trough and the discharging head and is spread on the road surface.

[0004] Regarding the above-mentioned related technologies, during the asphalt paving process, the asphalt flows out through the discharge trough and the discharge head, and is then spread on the road surface.
