This specification covers reinforced arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts. Pipe manufactured according to this specification shall be of three classes identified as Class A-II, A-III, and A-IV. The reinforced concrete shall consist of cementitious materials, mineral aggregates, and water, in which steel has been embedded in such a manner that the steel and concrete act together. The pipe shall be designed to meet both the 0.01 in. crack and ultimate strength requirements determined by conducting plant load bearing tests, material tests, and inspection of manufactured pipe for visual defects and imperfections. The reinforcement, joint, and manufacture are detailed.

1.1 This specification covers reinforced arch-shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, storm water, and for the construction of culverts.

1.2 This specification is the inch-pound companion to C506M; therefore, no SI equivalents are presented in the specification.

Note 1—This specification is a manufacturing and purchase specification only, and does not include requirements for bedding, backfill, or the relationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of this product depends upon the proper selection of the class of pipe, type of bedding and backfill, and care that the installation conforms to the construction specifications. The owner of the reinforced concrete pipe specified herein is cautioned that he must correlate the field requirements with the class of pipe specified and provide inspection at the construction site.
