Abstract: Apparatus and methods are described relating to barrel crash cushions which readily collapse when impacted from a substantially end-on direction, and are more capable than conventional designs of substantially redirecting vehicles impacting from non-end-on directions and reducing the chance of these vehicles tearing through the crash cushion. The described configurations also substantially reduce the harm associated with "coffin corner" impacts through a structurally reinforced portion that increases the ability of the barrel cushion to withstand impacts from directions other than substantially end-on.In some exemplary embodiments, the structural reinforcement is provided by a telescoping bracket assembly which surrounds some of the barrels of the crash cushion. In another embodiment, the reinforcement is provided by a plurality of interconnected cable sleeves which are carried on cables disposed along the longitudinal sides of the crash cushion to form a linear brace.

Abstract: An elongated roadway barrier deformable under impact to redirect a vehicle striking the barrier. The barrier includes a plurality of panels arranged in parallel, spaced rows to define a filler cavity. A filler material is disposed in the cavity to support the barrier and to provide a medium for dissipating impact energy. The filler material is stabilized by a bonding agent and has a shear strength of at least about 30 psi and a compressive strength less than about 1200 psi.
