  • Patent number: 4271555
    Abstract: Reinforced concrete bridge decking comprises a plurality of substantially identical, removable, interchangeable reinforced concrete panels having protruding tongues at opposite ends supported on and retained in place by resilient, shock absorbing pads. The panels each have a metallic frame substantially filled with concrete, and an abrasive material layer is bonded on the top surface of the concrete. The abrasive material layer provides a hard, salt resistant, anti-skid surface on the concrete panels, and also serves to strengthen the panels. The resilient pads are readily removable to release the individual panels, so that a tool can be engaged with the panels in the spaces defined between the tongues at the opposite ends thereof to remove the individual panels for maintenance or repair, or to interchange the panels with one another.
