  • Abstract:
    This report presents the results from an experimental investigation which explores the change in structural response due to the addition of near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) reinforcement for increasing the capacity of the edge region of a reinforced concrete bridge deck. The motivation for rehabilitating bridge deck overhangs using NSM reinforcement is to increase the load carrying capacity of the region so that the overhang can accommodate the larger than designed for loads caused by the installation of sound barrier walls onto the edges of the bridge deck. The experimental testing of an as-built reinforced concrete specimen without FRP was used as the baseline test to evaluate the effectiveness of the NSM CFRP strengthening scheme. Details regarding the capacity calculations, experimental setup, testing protocol and experimental results for the as-built specimen and FRP rehabilitated specimen are discussed in this report. This report also presents the NSM CFRP strengthening design options examined for achieving the desired capacity increase and evaluates the change in structural response of the rehabilitated system as compared to the as-built test specimen.
