Introduction to the different uses of road shot blasting machines

1. Used to improve the roughness and friction coefficient of asphalt pavement, thereby enhancing its adhesion and ensuring driving safety. At the same time, the attachments on asphalt pavement (such as fuel, engine oil, etc.) have nowhere to escape, thus improving the anti-skid performance of the pavement.
2. Anti corrosion coating for steel bridge deck
In China, the application of shot blasting technology in the anti-corrosion coating of steel bridges cannot be denied. Most bridges under construction and already built will choose to use shot blasting technology for surface cleaning and roughness treatment before anti-corrosion primer or other spraying. The shot blasting machine used for the Qingdao Cross Bay Bridge can achieve the steel plate cleanliness requirements of SA2.5/SA3 for the steel bridge deck treated by shot blasting technology, and can control the roughness to meet the user's painting requirements. The entire process is dust-free and easy to move. Both environmentally friendly and convenient.
3. Maintenance of tunnels
In China, cement concrete is generally used for the road surface inside tunnels due to considerations such as waterproofing, material flame resistance, and oil resistance. But this also places high demands on the anti-skid performance of long tunnel pavements. For the two problems that are still difficult to solve in China, shot blasting technology is a simple construction, low equipment investment, significant effect, and environmentally friendly treatment method.
In the waterproof pavement of concrete bridge decks, shot blasting technology has become a requirement of the process specifications in European and American countries, and is gradually being accepted in China, where shot blasting technology is used to maintain the concrete pavement.
4. Preventive maintenance of airport runways
The use of road shot blasting machines makes it easy and straightforward to remove tire marks and markings on concrete and asphalt runways. Removing tire marks (excluding rubber), removing markings, restoring and increasing the surface roughness of airport runways, and improving the friction coefficient of runways are all within the scope of treatment for road surface shot blasting machines. And in the process of handling, it is effortless, and the road shot blasting work is carried out in an orderly manner.
5. Municipal roads and paved surfaces
Various road pavements in the city can be cleaned using shot blasting machines to remove road signs and markings. For busy intersections, the road surface can be roughened to improve roughness and friction coefficient. Reduce problems in road construction. Therefore, the auxiliary role of road shot blasting machines in urban construction is gradually standardizing and making our lives more convenient.
