ABSTRACT:
A roadway barrier component adapted to be assembled on a supporting surface with corresponding barrier components removably connected to opposed ends thereof for forming an elongated dismountable roadway barrier for flanking a roadway, the barrier being deformable under vehicle impact to gradually redirect a straying vehicle coming into contact therewith. The barrier component includes a pair of panels to be positioned along a lower edge of each panel on such a supporting surface in laterally spaced relationship to define a filler cavity between their internal surfaces for receiving a displaceable ballast material to support the component on such a supporting surface and to provide a medium for dissipating impact energy during use, and panel connection means for removably connecting the panels together in their laterally spaced relationship; each panel having panel fitting zones for use in removably connecting the panels of the barrier component to panels of corresponding barrier components to form an elongated roadway barrier having at least one elongated outer surface which is generally smooth and free of outwardly projecting obstructions in at least one direction parallel to the length of the barrier; and the barrier component being adapted to provide a lesser impact resistance in a lower zone than in a central impact zone of the barrier component during vehicle impact therewith to combat vehicle ramping.
