Abstract:Research was conducted on four Oregon bridges overlayed with Latex Modified Fibrous Concrete (LMFC) in 1981. Problems immediately arose on the first overlay project while trying to finish the deck. The tining process tended to pull and tear the steel fibers on the surface, producing a rough and unpleasant ride. Concrete grinding was required to make the surface acceptable. Balling of the steel fibers in the concrete mix was also a constant problem in all of the overlays, with the balls having to be removed prior to finishing.
