Description

Asphalt paving equipment for concrete pavement

Technical Field

The utility model relates to the technical field of road paving, in particular to a device for paving asphalt on a concrete road surface.

Background Art

At present, some old concrete pavements are prone to damage such as subsidence, cracks, misalignment, and broken slabs. Long-term maintenance and repair will occupy a large amount of maintenance funds. Therefore, when upgrading and renovating old pavements, most of them add a layer of asphalt on the old pavement. Compared with the continuous repair of old concrete pavements, it is an effective renovation measure.

After searching, the patent with the authorization announcement number CN 218813091 U discloses an asphalt paving device for old cement concrete pavement to prevent solidification, including a base and a stirring assembly, a universal wheel is installed at the bottom of the base, and the stirring assembly for preventing asphalt solidification is arranged on the upper surface of the base, and the stirring assembly includes a stirring tank, a motor, a stirring shaft, a stirring rod, a stirring impeller, a jacket, a water injection port and a ring-shaped heating plate, a motor is installed on the top of the stirring tank, and the output end of the motor is connected to the stirring shaft, the upper end of the stirring shaft is provided with a stirring rod, and the lower end of the stirring shaft is connected to the stirring impeller, a jacket is installed on the outside of the stirring tank, and a water injection port is arranged at the upper right end of the jacket. The asphalt paving device for old cement concrete pavement to prevent solidification adopts the mutual cooperation between multiple components, prevents asphalt solidification through the stirring assembly, conveniently cleans the inside of the stirring tank through the spraying assembly, and cleans the road surface through the cleaning assembly, so that the asphalt is laid more closely.

After the asphalt is laid, the above-mentioned device only uses a road roller to compact the asphalt. However, due to the uneven road surface or uneven asphalt discharge, the asphalt laid on the road surface will appear stacked and undulating. In this way, when only a road roller is used to compact the asphalt, it is easy to cause uneven distribution of the compacted asphalt and poor compaction effect. Therefore, in order to solve the above-mentioned problems, we propose a concrete pavement asphalt paving equipment.
