Abstract:

Project 0-7041 represents a significant endeavor aimed at developing the NextGen Texas Bridge Deck system. Utilizing panel pairs reinforced with wire trusses, the need of bracket-supported deck overhangs is expected to be eliminated, which will reduce construction time and effort. Through a comprehensive research approach encompassing experimental testing and advanced analysis techniques, the project sought to evaluate the feasibility and performance of this innovative bridge construction method. Experimental tests conducted on wire truss partial-depth panels provided valuable insights into structural behavior under various loading conditions, revealing a ductile load response and highlighting the influence of wire truss span on overhang deflections. Full-scale bridge deck tests demonstrated the feasibility of implementing the system and the confidence about the strength/serviceability. Furthermore, fatigue testing elucidated the system’s endurance under cyclic loading, informing recommendations for reinforcement strategies and material selection. The culmination of these efforts resulted in a set of design recommendations and guidelines offering practical insights for implementing the NextGen Texas Bridge Deck system in accordance with TxDOT standards. These recommendations cover wire truss spacing, reinforcement details, panel dimensions, and construction considerations, providing engineers with valuable tools to streamline bridge construction processes and enhance overall project efficiency. Moving forward, the findings and recommendations from Project 0-7041 have the potential to transform bridge construction practices in Texas and beyond, offering a viable alternative to traditional methods and paving the way for safer, more efficient, and resilient transportation networks.
