The road shot blasting machine has three functions on cement concrete roads.
1. Expose potential cracks in cement concrete roads.
The main reason for the damage to the structure of cement concrete roads is the infiltration of water. The main way for water to penetrate into the interior of the road is through the cracks in the road. After the road cracks are found, they can be solved by methods such as seam expansion and plugging, direct grouting, etc., but the difficult solution is to find potential cracks. The cement concrete road cleaned by the road shot blasting machine can expose potential cracks after high-speed beating of the shot material, and waterproof the road in advance.
2. Increase the anti-skid property of cement concrete roads
After long-term use, the cement concrete road is polished and smoothed, which greatly reduces the anti-skid performance of the road surface and causes huge safety hazards. After the construction of the road shot blasting machine, the friction of the cement concrete road can be increased, the anti-skid performance of the road can be increased, the grip of the tire can be improved, and the occurrence of traffic accidents can be reduced.
3. Improve the bonding degree between the waterproof layer and the board surface
After the road shot blasting machine is shot blasted, the friction of the board surface is greatly improved. At this time, the paving of waterproof materials can greatly improve the bonding degree between the board surface and the waterproof material, and improve the waterproof quality of cement concrete roads.
The waterproofing of cement concrete roads is particularly important. Good road waterproofing can greatly increase the quality of the road. Pavement shot blasting machines are very suitable for dealing with the waterproofing of cement concrete.
