  • Method of preparing an aluminum bridge deck and an aluminum bridge deck configuration for receiving a wearing surface
    Patent number: 5836029
    Abstract: An aluminum alloy bridge deck construction is disclosed with a wearing surface applied thereto. The surface of the welded-together extrusions of the bridge deck is treated so that a tight bond is formed between the wearing surface and the extrusion surface. When splicing bridge deck segments together, the joint extrusions forming part of the bridge deck include a wearing surface dam on an upper surface thereof. The wearing surface dam acts as a separator between a wearing surface previously applied to the bridge deck surface prior to its splicing and a surface which receives the wearing surface after the joint is made in the field.
