Britpave has been calling for the increased use of concrete barriers for some time. VCBs have been used on limited sections of the M1 and the M25 where, since their installation, there have been no reported crossover accidents and, unlike steel barriers, no ongoing maintenance and replacement programmes.
'Concrete barriers have been proved to eliminate crossover accidents, ' says Jones. 'Despite evidence of vehicular impact on the sections of concrete barriers located on the M1 and M25, the barriers have successfully restrained the errant vehicle and have not been adversely damaged.
'This saves a fortune on the cost of barrier repair and replacement programmes and eliminates the disruption of motorway crash barrier repair roadworks.'
A further benefit is the long-life performance of concrete barriers, Jones points out. 'Compared to the short life of only 20 years for steel barriers, concrete barriers are designed to last for at least 50 years, ' he says.
'This and their minimum maintenance requirement make them the best long term cost solution.'
