Abstract
An energy absorbing roadway barrier for dissipating kinetic energy upon impact by a moving vehicle includes an elongated core of reinforced high density concrete having barrier anchor members attached from the elongated core to a position for anchoring the barrier. An elongated barrier portion is formed around the elongated core and around the core anchor members to form a road barrier. A process of making the energy absorbing roadway barrier for dissipating kinetic energy upon impact by a moving vehicle includes the steps of forming an elongated core of reinforced high density concrete then attaching the plurality of elongated core supports and barrier anchor members to the core then mixing a plurality of lightweight polymer pieces, such as chopped up rubber tire pieces or chopped up or preformed polystyrene pieces with a fiberglass, microsilica, sand, and portland cement and water, then forming the mixture in an elongated barrier mold of a predetermined shape around the elongated core and around each elongated core support anchor member and curing the mixture to form the road barrier.
