Description

Technical Field

[0002] In recent years, with the development of mechanization technology, some simple crack repair mechanical devices have emerged, such as compactors, hot patch machines, etc., which can improve the repair efficiency and quality. In the early stage of highway construction, crack repair work mainly relied on manual construction, such as manually cleaning cracks and filling repair materials. This method has low efficiency and it is difficult to guarantee the repair effect. After crack repair, compaction is required to integrate the repaired part with the surrounding road surface. Therefore, the crack repair and flattening device needs to have good flattening technology, such as hydraulic systems, vibratory rollers, etc.

[0003] Currently, due to environmental and external force factors, cracks often occur in the asphalt pavement of highways. Therefore, a crack repair and flattening device based on highway engineering is needed to repair and flatten the cracks on the highway. However, the existing crack repair and flattening devices require multiple processes when performing repair and flattening, which is cumbersome for staff to operate. Moreover, the existing crack repair and flattening devices cannot synchronously roll the filled cracks, and subsequent rolling treatment by staff is required, increasing the work intensity of the staff.
