Abstract

Abstract: Research presented in this paper is aimed to investigate the possibility of using a mobile concrete barrier based on a design of the Czech Hedgehog, which was a steel barrier developed before the Second World War to stop slow-moving armoured vehicles. The design is revisited using an ultra-high-performance fibre-reinforced concrete (UHPFRC) with additional steel reinforcement bars. Crash test experiments are conducted using an ordinary road vehicle moving at 48 km/h (30 mph). Final barrier design is capable of stopping the vehicle, although at least two rows of barriers were needed.
