[0002] Asphalt pavement is the most widely used high-grade pavement in road construction. It has the characteristics of being flat, dust-free, waterproof, and durable. Asphalt pavement is very easy to break and crack due to overloaded rolling such as overloaded vehicles after long-term use. Therefore, it is necessary to carry out daily maintenance and repair of the damaged pavement and re-lay asphalt, as shown in the existing patent technology: After searching, the China Patent Network discloses a municipal road asphalt paving maintenance device (public announcement number CN212582361U). During the asphalt paving process, this type of device adjusts the angle of the paving plate and changes the thickness of the asphalt paving through the transmission parts arranged in the operating box. A paving plate is installed between the operating box and the connecting plate, which can be used to lay the asphalt after it is discharged, avoiding the problem of asphalt accumulation.

[0003] However, there are still some shortcomings in the above-mentioned public patents and the road maintenance asphalt paving devices adopted in the existing market: the existing method of flattening the asphalt road surface after spreading by flattening with a flattening plate cannot effectively evenly distribute the accumulated asphalt, and it is very easy to cause the asphalt to be pushed forward all the time under the action of continuous thrust, and cannot be spread to the left and right, resulting in uneven asphalt paving. To this end, those skilled in the art provide an asphalt spreading device for road maintenance to solve the problems raised in the above-mentioned background technology. Utility Model Content
