Precast Deck Systems for Steel-concrete Composite Bridges ...

Composite bridges using precast bridge deck units have been constructed for over 40 years and can take many forms. Deck units may be either full-depth or partial-depth (requiring to be made composite with an in situ concrete topping), and may be connected at transverse joints using reinforced concrete, dry- jointed details or they may be post-tensioned longitudinally to provide continuity.
