Standard Specification for Reinforced Concrete D-Load Culvert, Storm Drain, and Sewer Pipe (Metric)
This specification covers reinforced concrete pipe, D-load culvert, storm drain, and sewer pipe for the conveyance of sewage, industrial wastes, and storm water. The numerical values in this specification are not presented in inch-pound units, but rather, in metric or SI units only. 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 combination of cementitious materials used in the concrete shall be only one of the following: Portland cement, Portland blast furnace slag cement, slag modified Portland cement, Portland pozzolan cement, a combination of Portland cement and fly ash, a combination of Portland cement and ground granulated blast-furnace slag, or a combination of Portland cement, ground granulated blast furnace slag, and fly ash. Reinforcement shall conform to the standard specification. Physical requirements shall conform to the design strength designation of the pipe during load test. The aggregates shall be sized, graded, proportioned, and mixed with such proportions of cementitious materials and water as will produce a homogeneous concrete mixture of such quality that the pipe shall conform to the test and design requirements of this specification. The strength of the pipe shall not be adversely affected by the splice. Compression tests for determining concrete compressive strength shall be allowed to be made on either concrete cylinders or on cores drilled from the pipe. Pipe shall be repaired, if necessary, because of imperfections in manufacture, damage during handling, or pipe that have been cored for testing.
1.1 This specification covers reinforced concrete pipe designed for specific D-loads and intended to be used for the conveyance of sewage, industrial wastes, and storm water and for the construction of culverts.
1.2 This specification is the SI companion to Specification C655; therefore, no inch-pound equivalents are presented in this specification. Reinforced concrete pipe that conform to the requirements of C655 are acceptable under this Specification C655M unless prohibited by the Owner.
Note 1: Experience has shown that the successful performance of this product depends upon the proper selection of the pipe strength, the type of bedding and backfill, the care that the installation conforms to the construction specifications, and provision for adequate inspection at the construction site. This specification does not include requirements for bedding, backfill, the relationship between field load conditions and the strength designation of pipe, or durability under unusual environmental conditions. These requirements should be included in the project specification.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
