Abstract

Abstract A barrier is manufactured by inserting a cage frame into the mold. The cage frame forms a clearance gap between the frame side walls and the mold side walls. The cage frame is first substantially filled with vehicle tire material and secondly filled with non-recyclable plastic material. An adhesive-type liquid is poured into the clearance gap to fill the sides of the mold. The top of the mold is coupled into place and the adhesive liquid is poured through the top to fill up the mold. The mold is then cured to produce the barrier.
