3、cation 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 SI companion to Specification C506.NOTE 1This specification is a manufacturing and purchase specification only
4、, and does not include requirements for bedding, backfill, or therelationship between field load condition and the strength classification of pipe. However, experience has shown that the successful performance of thisproduct depends upon the proper selection of the class of pipe, type of bedding and
5、 backfill, and care that the installation conforms to the constructionspecifications. The owner of the reinforced concrete pipe specified herein is cautioned that he must correlate the field requirements with the class of pipespecified and provide inspection at the construction site.2.
