Concrete bridge decking

steel

Description Concrete/steel hybrid decks consist of a combination of the open grid deck and the full depth precast deck panel systems. There are two common forms of this decking system: partially filled grid decks and exodermic decks. The partially filled grid decks involve casting concrete for the lower section of the deck and including the open grid. Later the rest of the deck will be poured on site. The exodermic decks involve the same process as the partially filled grid decks except that a majority of the concrete is placed above the steel grid. Application Concrete/steel hybrid deck panels are used as an alternative to cast-in-place concrete decks. They provide a driving surface for traffic. Constructability To connect the separate panels to one another, bolted or welded connections are used. Since the deck is very similar to a full depth precast concrete depth, welded stud shear connectors are used to connect the deck panels to the steel framing.
