This specification covers the requirements for the manufacture and acceptance of precast reinforced concrete sewer, storm drain, and culvert pipes made by direct design. The reinforced concrete should consist of cementitious materials, mineral aggregates, admixtures, and water, in which steel has been embedded in a way that makes the steel and concrete to act together. Joints should be designed and the ends of the pipe sections should be formed so that the pipe sections can be laid end-to-end to make a continuous line of pipes. A line of circumferential reinforcement may be composed of up to two to three layers, depending on the pipe wall thickness and shall be assembled into a cage containing sufficient longitudinal members. All pipes should be tested and made to comply with specified physical requirements.

1.1 This specification covers the manufacture and acceptance of precast concrete pipe designed to conform to the owner's design requirements and to ASCE 15 or an equivalent design specification.

1.2 This specification is the companion to SI Specification C1417M; therefore, no SI equivalents are presented in this specification.
