Standardized Precast Prestressed Concrete Panels for Bridge Decks

NUDECK is a full-depth precast prestressed concrete bridge deck system that has higher performance characteristics and lower life-cycle cost than conventional cast-in-place concrete decks. NUDECK panels are installed, post-tensioned, and connected to bridge girders in a significantly shorter duration than conventional decks due to the elimination of deck forming, reinforcing, curing, and stripping operations. The SKYLINE Bridge in Omaha, Nebraska was a pilot project for the first generation of NUDECK that demonstrated the advantages of this system. Several efforts are being devoted to improve this already efficient system by standardizing the NUDECK panels, eliminating the need for a deck overlay, and simplifying panel-to-panel and panel-to-girder connection details. This paper presents the modifications made to develop the second generation of NUDECK system along with its simplified design procedures. An additional ¼ to ½ inch sacrificial thickness is added to the panel to be grinded after panel installation for a smoother profile. A welded wire reinforcement mesh is added to the panel to speed up the fabrication and control cracks in both directions. Panels are developed as standardized units that accommodate bridges with different skew angles. Moreover, new NUDECK panels are produced using match cast to eliminate the grouting operation needed for transversal joints.
