• Abstract:
  Improved methods of bridge deck construction are greatly needed. Bridge decks are often the first element to require repair or replacement because of its direct exposure to the elements and tire wear. This report presents a new precast overhang system that allows for significant improvements in construction speed, economy, and safety while meeting the AASHTO requirements and providing a serviceable structure. Results also indicate that the system will allow a support beam to be removed in certain circumstances. Welded wire reinforcing were also investigated to replace tied reinforcing bars with partial depth panels to improve the economy, constructability, and construction speed of bridge decks. Bridge decks have been constructed and tested that have used tied reinforcing and welded wire mats. The improved ability of the wire mat to help resist cracking could allow an owner either greater construction tolerances for the reinforcement placement or improved crack control and hence long term durability.
