    Revision of C76M - 19 Standard Specification for Reinforced Concrete Culvert, Storm Drain, and Sewer Pipe (Metric)

    (What is a Work Item?)

    Active Standard: C76M - 19b

    Proposal to modify Table 5, Note B of ASTM C 76M to add a provision for a single circular cage for 600 mm Wall C with a reinforcing area of 5.7 cm/m. This is 42% more steel than a combined inner and outer circular cage and 125% more steel than a single elliptical cage. At least one producer has obtained both Class V 0.3 mm and ultimate strengths using a single circular cage of 4.2 cm/m (0.20 in/ft). An area 5.7 cm/m is proposed based on further analysis to minimize or negate factors such as closer wire spacing and/or higher concrete strengths that may have produced more favorable results for the 4.2 cm/m steel area tested. As with any of the Table 5 steel areas, a Class V pipe so manufactured is subject acceptance based on Section 5 of this standard.
