ABSTRACT
Near-surface reinforcement is a minimum disruption strengthening measure for masonry arch bridges. It consists of grouting stainless steel reinforcing bars into pre-drilled holes and presawn grooves in the exposed near-surface zones of the masonry where tensile stress levels are likely to result in cracking. This paper describes some of the recent uses of near-surface reinforcement for masonry bridge strengthening in the UK and provides a summary of recent analytical and experimental research and development.
