Abstract

The cost, traffic accommodation, schedule, construction and other considerations involved in selecting deck replacement material and type for a 550m long two lane suspension bridge in Alberta, are described. Traffic has to be maintained on at least one lane, without interruption. Cast in place concrete, precast concrete, partial precast concrete ,"Exodermic" panels and steel plate sandwich (SPS) panels were evaluated. An innovative design of full depth, precast prestressed concrete deck slab panels for use in new as well as replacement bridge decks, is described. The precast panels are prestressed by pretensioning in the transverse and longitudinal directions. These panels have soffits in the form of elliptical paraboloid and contain prestressing only at the ribs. The design, fabrication, erection and construction considerations involved in using these panels as deck replacement for this suspension bridge, are described. For the covering abstract of the conference see ITRD number E211521.
