[0002] Asphalt concrete is a relatively common pavement material, which is characterized by good water resistance, durability, toughness and crack resistance, and can adapt to the requirements of various complex road conditions. In the construction of asphalt concrete pavement, compaction is an indispensable part, but the existing pavement construction compaction devices still have some problems during use. For example, when repairing road cracks, the existing construction equipment cannot control the asphalt concrete cover thickness before compaction, and repeated feeding and compaction work are required, resulting in low efficiency.

[0003] For example, the Chinese patent publication number CN219930649U discloses an asphalt concrete pavement construction compaction device, including a load-bearing plate, the front and rear ends of the top right side of the load-bearing plate are fixedly connected with fixed columns, the opposite side of the fixed column is fixedly connected with a connecting rod, the opposite side of the connecting rod is fixedly connected with a mounting ring, the interior of the mounting ring is fixedly connected with a mixing barrel, the middle part of the top right side of the load-bearing plate is fixedly connected with a hydraulic cylinder, the driving end of the hydraulic cylinder is fixedly connected with a shell, and the top of the shell is fixedly connected with a motor. In the utility model, automatic unloading is achieved through the mutual relationship between the fixed column mounting ring, the mixing barrel, the hydraulic cylinder, the shell, the motor, the threaded rod, the dragon conveying blade, the concave hole, and the baffle. During the pressing process, if there is an area not covered by concrete, it can be covered with concrete through automatic unloading, saving the time wasted by manual unloading and improving work efficiency.

In addition, the thickness of the concrete cannot be controlled by automatic unloading, and repeated unloading and compaction are required. The operation is cumbersome and the practicality is low. Therefore, the present application provides an asphalt concrete pavement construction device to meet the needs. Utility Model Content
