Design and Execution of Wood-concrete Deck Bridge

In Brazil is growing demand of short and medium span bridges not only in the new agriculture borders but also in the secondary roads in advanced regions. Traditional timber bridge not always meet the requirements of quality, they demand continuing maintenance and adequacy to actual heavy traffic. Mixed wood-concrete deck bridge arises as a viable alternative, because of its low construction cost, low maintenance and its high strength and stiffness. This paper presents the studies, design, execution and results from static load tests on wood-concrete deck bridge build with Corymbia citriodora wood specie logs, treated with CCA against xylophages organisms, reinforced medium strength concrete and steel bar connection bonde-in wood with epoxy resin, as shear connectors, were all used in construction system. Loaded tests were performed six months after the release of traffic. Results of the load tests indicate that the bridge performance is satisfactory.
