Optimization of in situ construction of concrete decks: Flexure tests of compact splices of reinforcement between phases

This article presents a study of an alternative casting process for concrete bridge decks executed span-by-span through self-supporting launching falsework or Movable Scaffolding System, focusing on a reduction of the critical path of construction. The efficiency of non-standardized reinforcement splices is evaluated through pure flexure static tests. Noteworthy, due to its geometrically compact characteristics, these splices do not interfere with the movement of the internal formwork of the deck. These original tests demonstrate that such splice solution for connecting reinforcement represents a safe and economical stress transference alternative for different types of concrete classes and performances.
