With the increase in traffic volume, concrete bridges often suffer from diseases such as concrete becoming loose, falling off, and steel reinforcement rusting due to water seepage. One reason for this is that during the treatment of the concrete surface, residues were not thoroughly removed and the surface was not kept sufficiently rough, resulting in insufficient bonding strength between the waterproof layer and the bottom of the bridge deck. On urban roads, shot blasting machines can be used to clean them and remove signs and markings; For intersections with heavy traffic, the road surface can also be painted to improve roughness and friction coefficient. After shot blasting treatment, cement and asphalt tracks can remove tire marks and markings, restore surface roughness and increase friction coefficient. China fully recognizes the application of shot blasting technology in the anti-corrosion coating of steel bridges. Most bridges under construction or already built undergo shot blasting cleaning and surface treatment before spraying anti-corrosion primer or other coatings.
