Abstract:
1. In a process for forming concrete structural components for road and bridge construction, wherein the resultant concrete structural components have exposed rebars for the later integration with additional concrete and/or mechanical structural elements, said additional concrete and/or mechanical structural elements selected from the group consisting essentially of sound walls, harneanes, guard rails and any combination thereof wherein the improvement comprises: A. Providing an iron work array wherein said iron work array comprises both (1) rebars for embedding within, and reinforcing, a first concrete highway structure and (2) rebars for extending from within said first concrete highway structure, for integration within and reinforcing a second concrete highway structure, to be formed at a later time; B. Providing a machine assembly having a tunnel mold comprising a mold cavity defined by a plurality of molding surfaces for forming said first concrete structure having. both embedded and exposed rebus, wherein said tunnel mold has a leading or forward molding surface, a trailing or rear molding surface, and at least one elongate channel, through said mold cavity, extending from said leading or forward molding surface to said trailing or rear molding surface of said tunnel mold, said elongate Channel being of a sufficient height to accommodate passage of said extending rebars, through said mold cavity, from said leading or forward molding surface to said trailing or rear molding surface of said tunnel mold; C. Slip forming said first concrete structure by
