摘要:

The object of this paper is to share the experience gained from a 4-year rehabilitation program on a section of the F. G. Gardiner Expressway in Toronto. The paper describes the latex-modified shotcrete repairs at locations of rusting strands at beam soffits and the conversion of original simply supported spans into continuous beams with the resulting elimination of nearly three fourths of the expansion joints. The benefits of continuity, reduction of expansion joints, new reinforced deck slab, and new drainage system are discussed and essential cost figures are provided.Key words: concrete, prestressed, bridge, rehabilitation, expressway, transportation, urban, shotcrete, continuity, expansion joint, composite deck, epoxied dowels, drainage.
