[0002] Road engineering refers to the whole process of planning, design, construction, maintenance and management work carried out with roads as the object and the engineering entity involved. After the asphalt road is built and opened to traffic, it may cause cracks in the asphalt pavement due to the wear and impact of wheels, erosion and weathering by natural forces such as heavy rain and ice melting, as well as human destruction and certain defects left over from construction, so it needs to be repaired. The existing repair method is usually to first cut off the damaged asphalt pavement, then spread asphalt on the cut-off part of the asphalt pavement, and then use a roller to flatten the spread asphalt. When the asphalt is flattened, the asphalt at the pavement cut will move to the intact pavement outside the cut after being pressed down. Therefore, in order to ensure the flatness of the pavement after repair, the staff needs to hold a scraper and follow the roller to scrape the asphalt moved to the intact pavement back to the pavement repair site, and then use the roller to perform a second flattening. During this period, the staff needs to follow the roller to scrape the asphalt moved to the intact pavement back to the pavement repair site, which increases the labor intensity of the operator and increases the manpower input. Therefore, a road repair auxiliary device is proposed to address the above problems. Utility Model Content
