    TECH Ultra-High Performance Concrete for Bridge Deck .

    rehabilitation is thin, bonded ultra-high performance concrete (UHPC) overlays. As an overlay material, UHPC can provide both structural strengthening and protection from ingress of contaminates using a 1-inch (25-mm) to 2-inch (51-mm) layer of material. This minimizes required material volume and can minimize additional dead load on the bridge
