Description

Technical Field

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

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction.

[0003] Among the existing pavements in my country, old concrete pavements are prone to sinking, cracks, misalignment, broken boards and other defects, and long-term maintenance and repair will occupy a large amount of maintenance funds. Therefore, when upgrading and renovating old pavements, in the existing technology, adding a layer of asphalt on the old pavement is often used, which is an effective renovation measure compared to the continuous repair of old concrete pavements.

[0004] When laying asphalt, especially on urban roads, it is necessary to keep the road unobstructed, and it is not possible to use a large paver to directly lay asphalt pavement. Generally, a small paving device is needed to lay old roads in sections. When laying asphalt, hot asphalt that has been fully stirred and mixed is generally needed. Whether the stirring is sufficient can directly affect the quality of the asphalt layer structure. The general small paving device has a simple structure and function. Although it can also complete the asphalt laying work, it cannot keep the hot asphalt fully stirred, and the overall work efficiency is low.

[0005] In the published Chinese patent application, publication number: CN218263355U9, patent name: Asphalt paving device for concrete pavement, although the stirring blades are installed by a detachable shaft sleeve, after the hot asphalt is added once, the stirring device can be driven to rotate by the motor in the paving device, and the hot asphalt material can be stirred for paving operations to improve the fluidity of the material, so that the stirring effect is more sufficient, uniform, and efficient, and the asphalt layer is more uniform when the asphalt is continuously paved. However, when paving asphalt, it is necessary to flatten the asphalt so that the overall thickness of the asphalt is relatively uniform to ensure that the thickness of each point of the asphalt is uniform. This prior art has certain limitations, and it cannot effectively flatten the asphalt and cannot effectively ensure the uniform thickness of the asphalt. Utility Model Content
