OAK STREET BRIDGE DECK REHABILITATION

This paper was presented at the 'Innovative Bridge Projects, 1993 session. Vancouver's Oak Street Bridge was designed and construc in the 1950's and remains a key link in the BC Lower Mainland's transportation system. A major rehabilitation of the structure wa required in 1995 due to extensive deterioration of the two km lon bridge deck and the precast sidewalk panels. Recent traffic accidents on the bridge had highlighted important safety deficien that were corrected by cast-in-place concrete parapets and a prec median barrier. Other major project elements included: removal of existing asphalt and deteriorated concrete; addition of an overla high performance concrete, followed by a waterproof membrane, and asphalt. The deteriorated concrete on the underside of the bridg deck was also removed and patched, and the bridge deck expansion joints replaced. This paper describes the steps taken to address these issues.
