[0002] Expressways, abbreviated as highways, refer to roads specially designed for high-speed vehicle travel. They are asphalt pavements, which refer to various types of pavements paved with road-use asphalt materials in mineral materials. The asphalt binder improves the ability of the granular materials used for paving to resist the damage of vehicle traffic and natural factors to the road surface, making the road surface flat, less dusty, waterproof, and durable. Asphalt pavement is a widely used high-grade pavement in road construction.

[0003] In the construction and maintenance of expressways, the flatness of asphalt pavement is crucial for driving safety and comfort. In order to ensure the quality and flatness of the road surface, special asphalt pavement leveling devices will be used. The current position of the leveler is relatively fixed, which is not convenient to adjust the height of its bottom according to the actual situation, reducing the efficiency of the road surface leveling operation. Therefore, we propose a leveling device for highway asphalt pavement to solve the above problems. Content of the Utility Model
