Technical Field

[0001] The utility model relates to the technical field of asphalt leveling, in particular to a post-paving leveling device for asphalt in highway engineering. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, waterproof and durable. After the asphalt highway is paved, there will be bulges in some areas, which need to be leveled with a leveling device.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing post-paving asphalt leveling device for highway engineering does not have a good auxiliary asphalt removal function, and it is necessary to hold a small shovel manually, place the leveling plate upside down, and apply force to repeatedly move the shovel to scrape off asphalt impurities. This method is time-consuming and labor-intensive and urgently needs to be improved. Therefore, we propose a post-paving asphalt leveling device for highway engineering. Utility Model Content
