Impact-absorbing road side barrier - comprises paired panels forming space filled with bulk material, with greatest impact resistance towards top (BR 27.7.82)

摘要

The barrier component includes a pair of panels to be positioned along a lower edge of each panel on a supporting surface laterally spaced to define a filler cavity between their internal surfaces for receiving a displaceable ballast material. This provides a medium for dissipating impact energy during use. Panel connectors removably join the panels together in their laterally spaced relationship. - Each panel has panel fitting zones for use in removably connecting the panels of the barrier to panels of corresponding barrier components to form an elongated roadway barrier having at least one elongated outer surface which is smooth and free of outwardly projecting obstructions in at least one direction parallel to the length of the barrier. The barrier component provides a lesser impact resistance in a lower zone than in a central impact zone during vehicle impact, to combat vehicle ramping.(4/4)
