Standard Specification for Reinforced Concrete Elliptical Culvert, Storm Drain, and Sewer Pipe
This specification covers reinforced elliptically shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, and storm water, and for the construction of culverts. Pipe manufactured according to this specification shall be of five classes each for horizontal elliptical and vertical elliptical pipe with the following identification: Class HE-A, HE-I, HE-II, HE-III, and HE-IV for the horizontal elliptical pipe, and Class VE-II, VE-III, VE-IV, VE-V, and VE-VI for the vertical elliptical pipe. The prescribed strength requirements for the pipe are given in the specification. 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 this specification. In no case, however, shall the proportion of Portland cement, blended hydraulic cement, or a combination of Portland cement and supplementary cementing materials be less than a specified volume. The pipe shall be subjected to compression and absorption testing.
1.1 This specification covers reinforced elliptically shaped concrete pipe to be used for the conveyance of sewage, industrial wastes, and storm water, and for the construction of culverts.
1.2 Pipe designed for placement with the major axis horizontal shall be designated as “Horizontal Elliptical Pipe.” Pipe designed for placement with the major axis vertical shall be designated as “Vertical Elliptical Pipe.”
1.3 This specification is the inch-pound companion to Specification C 507M; 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.
