This specification covers reinforced concrete pipe intended to be used for the conveyance of sewage, industrial wastes, and storm water, and for the construction of culverts. Pipe manufactured in accordance with this specification shall be of five classes identified as Class I, Class II, Class III, Class IV, and Class V. Pipes shall conform to the design and strength requirements for diameter, wall thickness, and compressive strength. The acceptability of the pipe shall be determined by the results of three-edge bearing test, absorption test, material test, visual inspection, crushing test, and compression test. The aggregate shall be so sized, graded, proportioned, and mixed with such proportions of Portland cement, blended hydraulic cement, or Portland cement and supplementary cementing materials, or admixtures, if used, or a combination thereof, and water to produce a homogeneous concrete mixture of such quality that the pipe will conform to the test and design requirements of the specification. Pipe reinforcement methods considered in this specification are circumferential reinforcement, longitudinal reinforcement, and joint reinforcement. Pipe shall be subjected to either steam curing, water curing, or the two methods combined, provided that the required compressive strength is attained.
