Steel-fiber-reinforced concrete was used as a bridge deck overlay in Pennsylvania. This paper discusses the mixing and placing of that overlay on a single-span, continuous- truss bridge. Aside from a delay caused by the necessity for emergency bridge repair elsewhere, problems in placing the overlay included formation of wire balls in the concrete, nonuniformity of concrete loads delivered, and erratic strength test results. It is recommended that, on the steel-fiber-reinforced project to be undertaken by Pennsylvania, control sections be provided to afford more meaningful evaluations of concrete performance.
