With the aim of reducing construction costs and preserving the environment, efforts are recently directed toward rationalization and laborsaving of the structures and construction processes of steel road bridges. To approach the matter from the standpoint of materials, reactive powder concrete (RPC) that contains steel fibers has been developed. This concrete is not only very strong but it is also resistant to carbonation, chloride ion penetration, freezing, thawing, and abrasion. To promote the rationalization and labor saving of the reinforced concrete (RC) slabs of steel road bridges, the author proposes a composite structure that consists of RPC permanent form and RC slab and evaluates the usefulness of the structure as the slab of steel road bridges.
