STRENGTHENING OF THE QUINTON BRIDGES WITH EXTERNALLY BONDED STEEL PLATE REINFORCEMENT
The first major UK steel plate bonding application dates back to 1975 when four pairs of concrete bridges on the M5 Quinton interchange were strengthened. Two different epoxy adhesive systems were used. In January 1995, cores were taken through steel/concrete and steel/steel interfaces to examine the condition of a small fraction of the steel surfaces and to test the two adhesive materials. Variable bond line thicknesses, variable steel surface conditions and variable adhesion was found. It also appeared that there had been mixing and application problems with one of the adhesives, as evidenced by voiding and large colour variations. Light corrosion of the steel beneath this adhesive was also found in places. Nevertheless the cohesive properties of both adhesive materials were similar to their initial values and satisfactory structural performance was realised in lap shear joints.
