• Abstract:
  "The majority of today’s bridge decks are built using cast-in-place concrete construction. This is due to the perceived
  
  low initial cost and constructor familiarity with the system. This research report describes the design, details, and
  
  construction of an innovative full-depth precast concrete bridge deck system – the Second Generation NUDECK
  
  (Nebraska University Deck). The quality of this system is far superior to cast-in-place construction. Cast-in-place
  
  concrete bridge decks experience cracking shortly after construction due to differential creep and shrinkage with the
  
  supporting beams. This leads to bridge deck deterioration; a problem that is not experienced with the virtually crackfree
  
  prestressed NUDECK made from high performance concrete. Rapid construction and minimizing the impact to
  
  drivers are two major demands toward our transportation industry. Precast bridge deck panels remove the construction
  
  operation from the jobsite and replace it with bridge deck installation. This eliminates the time spent on forming,
  
  concrete placing, and concrete curing. In addition, it increases worker and driver safety. Applications of this system to
  
  two of Nebraska’s bridges are presented in this report."
