摘要:
A bridge replacement method is disclosed. The bridge includes a deck supported by a pair of abutments, each abutment having wing walls. The deck is removed, footings are cast in holes dug behind each abutment and a pier is provided on each footing. Substantially parallel and coplanar cambered beams are provided. Each beam spans between and is supported by the piers. A brace assembly reinforces the beam camber. On each adjacent pair of beams, precast deck elements are placed, such that each element of said plurality spans the beam pair, to define at least transverse gaps between the elements and put the upper surfaces of the elements in compression in a transverse direction. The gaps are grouted. After grout curing, the brace is adjusted to reduce the beam camber and cause the upper surface of the elements to also be put into compression in a direction parallel to the beams.
