TRL note on tests completed for ASSET – “Since the flanged base of the Asset VRS Varioguard extends 150 mm in from the traffic face the setback distance of the barrier can be reduced by 150 mm without adversely affecting the performance of the barrier. As a consequence, the Working Width can be reduced by a corresponding distance.”
