<p>An energy dissipating system is mounted on the side surface (16) of an elongated concrete median or roadway barrier (10) and includes a longitudinally extending flexible sheet (25) of low friction plastics material having upper and lower edge portions (32, 34) secured to the side surface (16) of the barrier (10). The flexible sheet (25) defines a longitudinally extending cavity (42) therebetween. An elongated energy dissipating member (45) extends horizontally within the cavity (42). The dissipating member (45), in one form, comprises a set of resilient cylindrical tubes (45) of extruded plastics material with a smaller tube (52) enclosed within a larger outer tube (48).</p> |
