Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road engineering, in particular to a multi-layer compacting device for repairing road cracks. Background Art
[0002] Pavement cracks develop due to long-term exposure to factors such as vehicle traffic, climate change, and ground settlement. To repair these cracks and restore the road's smoothness and durability, a specialized repair device, a repair compactor, is used. This device applies high pressure to fill the cracks with specialized repair material, then compacts it to ensure it is fully filled and firmly bonded to the surrounding road surface. The repair material, typically a specially formulated asphalt mixture or polymer, offers excellent durability and adhesion, effectively sealing cracks and resisting the effects of vehicle traffic and weather. Once repaired, the road's smoothness is restored and cracks are effectively sealed, extending the road's service life and improving driving safety.
[0003] However, the existing multi-layer compaction device for repairing pavement cracks cannot adjust the compaction intensity. Due to the lack of adjustment function, the compaction intensity cannot be flexibly adjusted according to different pavement conditions and crack degrees, resulting in excessive or insufficient compaction during the repair process, affecting the repair effect and pavement quality; in addition, the lack of adjustment function will also increase the complexity and cost of use, limiting its applicability and flexibility in different scenarios.
