Variable Profile Concrete Step Barrier (VCSB) The variable profile is a development of the standard fixed profile barriers for use in the central reserve where adjacent carriageways are constructed at different levels. Variable profile barrier overcomes the need to provide twin lengths of barrier one servicing each carriageway as is the case with any other safety restraint system. VCSB - The Concept Uniquely the sides of Britpave variable profile concrete barrier are aligned to suit the road surface level of each carriageway so that the relationship between the step profile and the road is maintained. Britpave variable profile barrier can accommodate an adjacent carriageway level difference of up to 300mm; above this twin barriers must be used. Britpave variable profile barrier is available in both CSB and WCSB in the event that street lighting is required along the central reserve.
