Abstract
The authors have developed a steel-plate concrete composite deck for highway bridges. The composite deck consists of steel plate, upper re-bars and concrete. The steel plate has to have lateral direction joints with every 2 or 3 meters. In usually, as such joints have been fastened by high strength bolts at construction site, it is necessary to set scaffoldings under the steel plate. In order to decrease construction costs and to improve safety at site works for the composite deck, the authors propose an adhesive joint with epoxy resin for the steel plates, which can fasten up by only upper side works on the plates. In this paper, performance for the adhesive joint is investigated through static and fatigue coupontests, and wheel running test with slab speciments.
