Description

Technical Field

[0001] The utility model belongs to the field of road surface maintenance, and in particular relates to a road micro-surfacing preparatory maintenance device. Background Art

[0002] The road micro-surfacing preventive maintenance device is a device used to maintain and extend the life of roads. Its main function is to perform preventive maintenance on roads through micro-surfacing technology, thereby improving the flatness and anti-skid performance of the road surface, while reducing the occurrence of cracks and other damage.

[0003] Micro-surfacing is a typical preventive maintenance measure and another level of protection for old asphalt pavements. When measures such as fog seal or micro-crack sealing cannot meet the requirements of protecting the pavement, and the old pavement structure has sufficient strength reserves and no obvious structural defects, micro-surfacing measures can be used. The biggest difference between micro-surfacing and slurry seal is that micro-surfacing uses modified emulsified asphalt, which has a much faster demulsification rate. In addition, strict grading is used, and its durability and wear resistance are stronger than slurry seal.

[0004] The main purpose of micro-surfacing is to: improve the structural depth of the road surface and enhance the anti-skid performance of the road surface; seal water seepage under the road surface to prevent water erosion and damage to the road base; repair shallow ruts; make up for the oil deficiency of the asphalt surface layer and repair the function of the asphalt surface layer; it is faster than hot asphalt construction and can be opened to traffic in about an hour, reducing the impact of construction on traffic.

[0005] To sum up, in actual road maintenance, the mixed maintenance paint is usually sprayed on the road surface, but the maintenance paint is very easy to precipitate during long-term use, which is easy to clog the spraying structure and affect the effect of the device on road maintenance. In addition, due to the different thicknesses of the maintenance paint sprayed, the required leveling angles are often different, but the fixed-angle leveling structure is difficult to flexibly adjust the leveling structure.

[0006] Therefore, in view of the problems that when the above-mentioned maintenance device is used for road maintenance, its maintenance coating is very easy to precipitate during use, and these precipitates will clog the spraying structure on the maintenance device, and its fixed leveling structure is difficult to adjust the leveling angle of the leveling structure according to the thickness of the maintenance coating, a road micro-surfacing pre-maintenance device is developed. By adding a stirring structure, a rotation-adjustable leveling structure, a uniform spraying structure, a roller compaction structure and a moving structure to the maintenance device, the effect and efficiency of the device for road maintenance can be greatly improved, and the leveling angle can be flexibly adjusted according to the thickness of the maintenance coating, and the stability of the device when moving is improved.
