Iowa Method of Partial-Depth Portland Cement Resurfacing of Bridge Decks

Source

Low-slump, high-quality concrete is used in Iowa for partial-depth patching and resurfacing of bridge decks. All unsound concrete is removed, as well as a minimum of ¼ in. (0.054 m) of the remaining sound concrete surface. Sand cement grout is scrubbed onto dry, prepared deck immediately prior to compacting low-slump concrete into place using vibrating screeds.
