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.
