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.
