The pavement shot blasting machine can remove the floating slurry and impurities on the surface of the concrete at one time, and can roughen the surface of the concrete to make the surface uniform and rough, which greatly improves the adhesion strength of the waterproof layer and the concrete base layer, so that the waterproof layer and the concrete base The better combination of the bridge deck can also fully expose the cracks in the concrete, which has the effect of preventing problems before they happen.


1. Used to improve the roughness and friction coefficient of the asphalt pavement, thereby improving the adhesion of the road surface, to ensure the safety of driving. At the same time, the attachments (such as fuel, engine oil, etc.) on the asphalt pavement have nowhere to escape, which can improve the anti-skid function of the pavement;


2. Anti-corrosion coating of steel bridge deck
In our country, the application of shot blasting technology in the anti-corrosion coating of steel bridges cannot be denied. Before applying anticorrosive primer or other spraying, most of the bridges under construction and already built will choose to use shot blasting to clean and roughen the surface. The shot blasting machine used in Qingdao Cross-Bay Bridge, shot blasting process to treat steel bridges The surface can reach the steel plate cleanliness requirements of SA2.5/SA3, and it can control the roughness to satisfy the user's coating requirements. The entire process is dust-free and easy to move. Both environmentally friendly and fast.


3. Authentic protection
In my country, cement concrete is generally used for road surfaces in tunnels due to considerations of waterproofing, fire and oil resistance of materials. But this also puts forward higher requirements on the anti-skid function of the long road surface. Regarding the above two problems that are still difficult to solve in our country, the shot blasting process is a simple construction, small equipment investment, significant effect and environmental protection.

In the waterproof paving of concrete bridge decks, the shot blasting process is already required by the European and American process standards, and is gradually being accepted in China. Shot blasting processes are used to protect the concrete pavement.


4. Preventive maintenance of airport runways

The use of pavement shot blasting machine makes it easy and simple to remove tire tracks and markings on concrete and asphalt runways. Except for tire tracks (except rubber), removing markings, restoring and increasing the surface roughness of airport runways, and improving the friction coefficient of the runway are all within the processing range of the road shot blasting machine. Moreover, in the processing process, the road shot blasting work was carried out in an orderly manner.


5. Municipal roads and paved roads

All kinds of road paving in the city can be cleaned with shot blasting machines to remove road signs and markings. At intersections with heavy traffic, the road can be roughened to improve the roughness and friction coefficient of the road. Reduce problems in road construction.
