[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 pavement caused by traffic and natural factors, and the pavement has the advantages of being flat, dust-free, impermeable, and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in municipal road construction; in the paving and maintenance of asphalt pavement, since the asphalt structural layer is a flexible pavement, the paving and compaction process will cause uneven roadsides, so trimming operations are required.

[0003] The cutting blade of a traditional road trimming device is generally fixed at a fixed distance from the ground, and the cutting depth of the cutting blade cannot be directly adjusted. In the process of trimming the road surface, it is easy for the cutting depth of the cutting blade to be uneven due to changes in the terrain, and secondary cutting is required when necessary, which wastes people's time and physical strength and brings inconvenience to people during road construction.

[0004] Therefore, we propose a road maintenance edge cutting device. Utility Model Content
