CA 2306295

A precast concrete slab for forming a deck in a bridge superstructure has a chamfer on forward and trailing edges so that adjacent slabs can mate. The slab is reinforced with bars which protrude laterally from the slab on opposite sides and which, in use, extend over support beams. Selected bars are formed in a castellated shape of which inverted U-shaped portions extend above the surface of the precast concrete slab. Conveniently, the U-shaped portions anchor a concrete topping which is poured over the slabs at a bridge site and also provide locations for hooking a crane used to transport the slab at a site.
