Description

Technical Field

[0001] The utility model relates to the technical field of asphalt concrete paving, in particular to a paving device for asphalt concrete. Background Art

[0002] Asphalt concrete is commonly known as asphalt concrete. It is a mixture made by manually selecting mineral materials, crushed stones or crushed gravels, stone chips or sands, mineral powders, etc. with a certain gradation composition, and a certain proportion of road asphalt materials under strictly controlled conditions.

[0003] The specific proportion and preparation method need to be adjusted according to the engineering requirements. The prepared asphalt concrete is poured onto the road surface. Before compaction, the asphalt needs to be paved flat. When laying asphalt concrete, it is usually leveled by hand, and then a road roller is used to compact the asphalt road surface. The road roller compacts the asphalt concrete through the weight and vibration of the rollers to make it more compact and firm. Paving is an important step in the construction process of asphalt roads, which ensures the flatness and uniformity of the laid asphalt concrete.

[0004] However, if the asphalt concrete is not properly laid or not properly leveled and the slope is not controlled during the paving process, it may cause the road surface to be uneven, affecting the driving smoothness and comfort, and may increase the difficulty and risk of vehicle driving.
