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.
