Functions of Mobile Shot Blasting Machines
Mobile shot blasting machines are used for asphalt pavement maintenance. One of the most widely applied areas of shot blasting equipment is to increase the roughness and friction coefficient of asphalt pavement, thereby enhancing pavement adhesion to ensure driving safety. Simultaneously, various attachments on the asphalt surface are thoroughly removed.
The main applications of mobile shot blasting machines are reflected in the following aspects:
Pre-treatment for Asphalt Concrete Overlays: During overlay construction, using the shot blasting process for surface pre-treatment ensures the pavement is clean while increasing surface roughness. This strengthens the bonding between the overlay and the original pavement, significantly enhancing the structural durability. For slurry seals and resin overlays, prior shot blasting treatment greatly improves the adhesion strength between the resin overlay and the base layer, enhancing the quality of the slurry seal and extending the pavement's service life.
Direct Application on Asphalt for Anti-skid Improvement: The shot blasting process can be directly applied on existing asphalt pavements, such as texturing surfaces on curved sections to improve skid resistance.
Removal of Surface Bleeding: Asphalt surface bleeding can be directly removed through this process, thereby improving the pavement's skid resistance.
Road Marking Removal: Road markings can be completely eliminated under the action of the shot blasting process. In China, accidents caused by slippery road surfaces are increasing but have not yet received widespread attention. This equipment can flexibly treat small sections, restoring the pavement's skid resistance and providing a reliable guarantee for traffic safety.
The asphalt surface treated with the shot blasting process not only cleans off various surface attachments but also increases the surface roughness, thereby improving the performance of the asphalt pavement. Furthermore, the equipment is simple, convenient, and flexible to operate, allowing the surface cleaning work to proceed in a reasonable and orderly manner.
The above provides a detailed introduction to the functions of mobile shot blasting machines.
