N2 - Self weight is one of the primary criteria for the design of moveable bridge decks. Light-weight decks are preferred because they are less demanding on lifting machinery. Several light-weight deck systems have been proposed during recent years; however these systems are either over weight or have other associated problems especially with the long-term performance. Materials with high strength-toweight ratio like ultra high performance concrete, fiber reinforced polymers and aluminum have a great potential to be used for moveable bridge decks, because they result in lighter sections. This research work is focused on experimental evaluation of a light weight bridge deck system made of ultra-high performance concrete. The deck system was initially designed and tested as a simply supported single-unit deck strip with different end anchorages, flexural, and shear reinforcements. Subsequently, testing was expanded to include two-span single-unit and finally to two-span multiunit specimens. The system was tested under an AASHTO prescribed HS 20 truck loading, both at service and ultimate load levels. Results from experimental analysis confirm that the proposed system has excellent performance from both a strength and serviceability point of view.
