• 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.
