• Abstract:
  The first generation of precast concrete deck system, NUDECK, developed by the University of NebraskaLincoln (UNL) for Nebraska Department of Roads (NDOR), was implemented on the Skyline Bridge, ; Omaha, NE in 2004. The project was highly successful and received two PCI Awards of Excellence. The ; second generation of precast concrete deck system NUDECK was developed recently to further simplify ; precast panel/girder production, speed up bridge superstructure construction, and improve deck durability. ; The second generation of NUDECK consists of full-width full-depth precast concrete deck panels that are ; 12 ft long to minimize the number of deck panels and transverse joints, and consequently accelerate bridge ; construction. It also uses covered individual pockets and bundled shear connectors at 4 ft spacing to ; simplify panel and girder production and eliminate the need for deck overlay. Precast deck panels are pretensioned in transverse direction and post-tensioned in the longitudinal to enhance deck durability to ; achieve the same service life of other bridge components. ; This report presents the first implementation of the second generation of NUDECK system to the Kearney ; East Bypass project in Kearney, NE. The project consist of twin bridges: the south bound bridge constructed ; using conventional cast-in-place deck; and the north bound bridge constructed using the 2nd generation ; NUDECK system. Each bridge is a two-span continuous bridge that is 41 ft 8 in. wide and 332 ft long. ; Each span is 166 ft long and consists of five precast/prestressed concrete girders (NU1800) at 8 ft 6 in. ; spacing. This report presents the analysis, design, and detailing of the bridge superstructure. It also ; summarizes the experimental investigations conducted to evaluate the proposed design and construction ; details.
