Use concrete having a minimum compressive strength of 6,000 psi at the time of acceptance. Use Wall B or Wall C as necessary. When using one line of reinforcement, place it 1/2 of the shell thickness from the inner surface of the pipe. When using 2 lines of reinforcement, place each line so that the nominal protective covering of concrete is one inch from the outer surface of the pipe and 1 3/4 inches from the inner surface. The Department will allow a variation tolerance of ± 1/2 inch with a minimum protective covering of one inch from the inner surface in all cases.
810.03.06 Identification and Markings. Mark pipe sections according to AASHTO M
170 or M 207 as applicable for identification. For a ll pipe sizes greater than 30 inch diameter, mark the inside wall with a stencil identifying the class of pipe.
