The shot blasting process is implemented in the highway
With the development of road maintenance in my country, different functional layering materials are gradually being used. For example, slurry dust sealing, micro-surface, asphalt recycling coating, colored asphalt, etc., but all pavements face the problem of combining with the original base surface. "Technical Specification for Construction of Highway Asphalt Pavement" JTJ032 states that the sticky layer asphalt must be sprayed before the overlay construction. When conditions permit, it is best to use mechanical roughening to clean up before spraying sticky asphalt.
Going back to the past, the treatment method of the old pavement was only cleaning and flushing, which could not solve the fundamental cleaning of the base, a certain texture depth, friction coefficient, the exposure of cracks in the old pavement (to be repaired in advance), and cleaning the gap between the aggregates as much as possible. Therefore, there is an urgent need for a process to solve the above problems, and the advent of the shot blasting process can provide a solution to the above problems.
There are many maintenance techniques for asphalt pavement. No matter what maintenance technique is adopted, the quality of the interface treatment will directly affect the final project quality. Chengdu Shugong Machinery Co., Ltd. is bold and innovative. Through the improvement of the road shot blasting machine, the shot blasting process has been successfully applied to the maintenance of the asphalt concrete pavement. The use of the shot blasting machine to treat the asphalt pavement can greatly improve the cleanliness and Friction coefficient, especially suitable for thin-layer curing processes such as fog sealing layer, leaching regeneration, and regeneration sealing water layer. The pavement shot blasting machine can completely remove the failed asphalt bonded on the surface aggregate, completely expose the aggregate, and obtain a clean and rough surface.
The vast majority of highways in my country are asphalt pavement, so the maintenance of asphalt pavement is more important. The road shot blasting machine will also develop rapidly in the direction of modernization, intelligence and diversification with the development of maintenance technology. In the future, shot blasting technology will have good social and economic benefits. let us wait and see!
