Description

Technical Field

[0001] This utility model belongs to the technical field of road construction equipment, and more specifically, it relates to a high-efficiency asphalt paving thickness control device for municipal road construction. Background Technology

[0002] Asphalt pavers, as core equipment specifically designed to evenly spread hot-mix asphalt materials on road surfaces, play a vital role in modern road construction and maintenance. They not only significantly improve road construction efficiency and ensure uniform distribution of asphalt mixtures, but also significantly enhance road surface quality and durability. In actual construction, the asphalt paving thickness needs to be flexibly and promptly adjusted according to different ground conditions, road conditions, and design requirements. Construction workers primarily rely on measuring tools, such as thickness gauges, to manually measure the asphalt paving thickness. This method is extremely labor-intensive, time-consuming, and inefficient, especially for long road surfaces. Therefore, an asphalt paving thickness control device is needed to facilitate the construction of municipal roads.

[0003] Based on existing technology, it has been found that during the construction of existing municipal roads, asphalt is usually spread directly by controlling the leveling equipment. However, since the leveling frame is mostly in a fixed state, it is not convenient to control the asphalt paving thickness, making it easy to use. Utility Model Content
