The Development of Concrete Safety Barriers in France

Paper by CBAUCBOT POTIER from ISCR 6th 1990

The use of concrete safety barriers is currently increasing considerably. The area of use, limited for a long time to urban or suburban carriageways, has now spread to the whole of the road network. The appearance of sites longer than 10km had led companies to work in a different manner, using placer-spreader and mobile concrete plant. Another area of use has also been opened to concrete safety barriers: motor racing circuits. These barriers, 1.2 metres high, are constructed to withstand the impact of vehicles travelling at almost 300 km/h and are therefore heavily reinforced.
