Over 40% of the bridges in the USA need repair or replacement. The use of near-surface mounted (NSP) fibre-reinforced polymer (FRP) for repairing reinforced concrete (RC) structures is described. The technique involves embedding a bar into a groove half-filled with epoxy paste. Demonstration of the technique by the University of Missouri-Rolla on a bridge on Martin Springs Outer Road, Phelps County, Missouri is described. Load restrictions were placed on the bridge in 1985 due to a lack of transverse reinforcing steel. Details are given of the strengthening process to provide the necessary transverse reinforcement and of the approximate costs. The bridge will be field-tested elastically before and after strengthening.
