Long-Term Performance Evaluation of NUDECK

The Kearney East Bypass is the first bridge project that uses the 2nd generation of precast concrete deck system (NUDECK) and the only bridge in Nebraska with precast concrete deck panels on precast/prestressed concrete I-girders. The 2nd generation of NUDECK has several developments over the 1st generation that was implemented in Skyline Bridge in 2004 on steel I-girders. These developments include increasing the width of precast concrete deck panels from 8 ft to 12 ft, using covered individual pockets at 4 ft spacing instead of continuous open channel, eliminating deck overlay, and placing post-tensioning strands underneath the deck panels. The bridge will be constructed during the 2014-2015 construction seasons. In this research project, it is proposed to inspect, monitor, and evaluate the performance of the Kearney East Bypass bridge project for at least 3-year period, possibly 5-year period, after completion. During this period, the bridge deck is in service and exposed (no-overlay), which is an ideal condition to conduct detailed inspection for transverse joints, post-tensioning anchor zones, and deck-girder connections. Wireless gauges will be also installed to continuously monitor girder and deck deformations to confirm their behavior as composited sections. This long-term monitoring will provide vital information about the performance of the 2nd generation of NUDECK system.
