Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement maintenance, in particular to an ultra-thin wear layer asphalt pavement maintenance device. Background Art

[0002] Asphalt pavement is the most widely used high-grade pavement in road construction. Asphalt pavement is prone to damage under the long-term action of vehicle loads. In order to economically and quickly extend the service life of asphalt pavement, an ultra-thin anti-skid and wear-resistant layer is added to the pavement for maintenance. The laying of the wear layer can improve the pavement's quality of use and resistance to damage, and ensure road driving safety.

[0003] In the process of laying the wearing course with existing maintenance equipment, the additional paving material is first poured on the road surface by a moving mechanism, then leveled by a spreading mechanism, and finally leveled by a flattening machine. When laying the additional paving material, the additional paving material is concentrated and piled together, which makes it inconvenient to evenly lay the exported wearing course material toward the roadside, resulting in inconsistent heights of the wearing course material spread on the asphalt road surface, affecting the uniformity after leveling.
