Evaluation of Repair Techniques for Impact Damaged Prestressed Beams

Bridges in the Commonwealth of Virginia and other states are often damaged by impact with over-height vehicles. The impact damage may be relatively superficial or quite extensive. For precast, prestress concrete beams, superficial damage may be repaired with cosmetic methods such as shot-crete or patching with repair grouts. More extensive damage may require splicing of severed prestressing strands, or strengthening with steel plates or fiber reinforced polymer (FRP) layups. External prestressing and near-surface-mounted FRP repairs are also possible. Virginia does not have in place a policy for evaluation of impact-damaged girders. A guideline to assist in the evaluation of the severity of the damage, and to recommend repair techniques appropriate for various damage levels is needed to consistently, efficiently, and economically address impact damage.
