Comparison between shot blasting process and traditional process

Shot blasting technology is widely used in surface treatment of road and bridge construction abroad. In recent years, it has also been gradually promoted and used in China. In the traditional surface treatment of road and bridge construction in China, the main methods used are artificial chiseling, mechanical chiseling, and high-pressure water. All of them have low efficiency and serious environmental pollution. Even the original concrete surface has micro cracks due to strong vibration, which is inconvenient. Large area mechanized construction, the problem of poor adhesion.

Using traditional chiseling and milling processes for concrete road surface treatment, it can be seen that under high-speed impact, micro cracks are easy to occur in the concrete; the outstanding aggregate vibration is loosened; the cleaning is not thorough; the treated surface is uneven; the environment The pollution is serious; the subsequent cleaning work is heavy.

The surface treatment of the concrete pavement using the shot blasting process can be seen: the treated surface is beautiful and smooth, and there is no blind area; the original concrete base is little affected, the aggregate is not loose; the roughness is uniform and controllable; the environmental pollution is small; Subsequent cleaning work is small; the adhesion of the subsequent pavement process is good.

In the cleaning of pavement markings, the effects of using the milling process and the shot blasting process can be seen respectively. The shot blasting process has a great advantage over the traditional process. It can provide clean, tidy, 100% cleaning, and does not damage the original pavement. The best process with structure and a certain degree of roughness.
