Method for repairing crack and faulted slab at longitudinal joint part of cement concrete pavement
The invention discloses a method for repairing a crack and a faulted slab at a longitudinal joint part of a cement concrete pavement. The method comprises the following steps: grooving the cement concrete pavement in a direction perpendicular to the longitudinal joint; placing a twisted steel pull rod in the groove after clearing concrete and impurities in the groove; selecting a groove filling material for backfill. The method further comprises a step which needs to be added to repair the faulted slab defect at the longitudinal joint part. The method for repairing the crack and the faulted slab at the longitudinal joint part of the cement concrete pavement can effectively delay related defects caused by too-wide longitudinal joint and the faulted slab from occurring, prolong the service life of the cement concrete pavement, effectively restore load transferring capability between longitudinal joints, and improve driving safety.
