Abstract:All culverts with openings of more than 20 ft (6.1 m), measured parallel to the roadway, must be inspected on a two-year cycle in accordance with the National Bridge Inspection Standards (NBIS). Many highway agencies also inspect smaller culverts on the same cycle. The NBIS, and prudent engineering, requires that culverts that are structurally weak or hydraulically inadequate be inspected on a more frequent cycle. This manual has been developed to provide guidance to highway agencies on procedures that may be used to repair a wide variety of types of problems that beset metal and concrete culverts of all types. Many of the procedures are also applicable to the repair of timber and stone masonry culverts. Procedures are also presented on ways to improve the inlet and outlet ends of culverts as well as the streambed channels leading to and from them. Information presented in this manual has been compiled from numerous contacts with representatives of the culvert industry as well as many highway agencies through the United State and Canada.
