[0002] Repairing cracks in roads and bridges is an important measure to ensure the safety of road and bridge structures and extend their service life. There are a variety of repair methods to choose from for different types of cracks and bridge structures: surface repair method: suitable for smaller cracks or cracks that have no significant impact on the structural bearing capacity; grouting method: suitable for cracks with larger width and shallower depth, and situations where the integrity of the structure needs to be improved.
