  • Repair and Rehabilitation of Rigid Concrete Pavements

    The repair and restoration of rigid pavement depends on the type of distress. Cracking is the most common feature of the rigid pavement. Pumping, faulting, spalling, shrinkage, polished aggregates, punch out, deterioration of joint load transfer system, corner break, alkali-aggregate reaction, pop-outs and blow-ups are some the other causes ofPavement Repair Methods Penhall,Dowel Bar Retrofit (DBR) is a method of pavement repair that helps to re-establish a pavement’s load transfer integrity by placing steel, epoxy-coated dowels into already existing concrete across joints and cracks. The concrete is cut using a diamond-tipped blade and slots are created.
