<p>-l- ENERGY ABSORBING BARRIER An energy absorbing barrier for dissipating kinetic energy upon impact by a moving vehicle. The barrier comprises walls defining a container closed except for a fill opening to admit water. The side walls are resiliently deformable to return to their original shape after being struck, and include longitudinally extending, vertically spaced apart traction spoiler channels to reduce the area of contact between the barrier and the tires of a vehicle. The end walls include fittings for end coupling of a barrier to like barriers. The fittings permit adjacent barriers to be located at different heights to accommodate gradual changes in terrain elevation, and end couplers enable arrangement of end coupled barriers in curvilinear and other configurations.</p> |
