Steel fiber reinforced concrete, a relatively new type of concrete, contains thousands of small worries the size of common straight pins per cubic foot. Tests have indicated that this concrete can develop more than triple the normal bending resistance of ordinary concrete. Undoubtedly, such a characteristic will create more applications for structural concrete. Highway engineers are also beginning to foresee the use of steel fiber reinforced concrete for bridge deck construction because of a potentially double bonus- high flexural strength and the low dead load of a thin slab. In June 1972, the Minnesota Highway Department, undertook to construct experimentally the first deck overlay in the United States. The site selected was a badly deteriorated deck of a triple-span bridge located on County Highway 17 in Winona, Minnesota. The overlay with an average depth of three inches required approximately 35 cubic yards of fibrous concrete. The bridge deck overlay at Winona, Minnesota, may prove to be a significant step in the solution to the age-old problem of bridge-deck deterioration. Certain precautions must be taken in the batching, placing and testing of steel fiber reinforced concrete. One, recommended mix proportioning procedures must be adjusted to meet the requirements for workability or placability. Two, fibers should be mixed with aggregate before adding cement and water to obtain uniform concrete and eliminate bailing. Three, mixing water adjustments must be established partly by judgement since consistency is not directly related to the measured slump of the concrete. Four, vibrating screeds should be used to overcome the resistance of the fiber in fresh concrete to movement. Five, brooming to achieve the desired surface texture should not be done too early.
