Beam End Repair for Pre-stressed Concrete Beams

Precast Prestressed Concrete Beams (PPCB) have been a popular and economical choice for bridge superstructures for many years. Unfortunately, where the ends of the beams are subject to contamination from deicing chemicals, there has been accelerated deterioration of the concrete. As this deterioration continues, it eventually compromises the structural capacity of the beam. To address this critical issue, the proposed project investigates rehabilitation methods for restoring the full capacity of the beam with the ultimate goal of extending the service life of the bridge. A special effort will be made to particularly identify retrofit concepts appropriate for typical beam seats at abutments and pier caps.
