    Revision of C478M - 13 Standard Specification for Precast Reinforced Concrete Manhole Sections (Metric)

    (What is a Work Item?)

    Active Standard: C478M - 13

    Developed by Subcommittee: C13.06 | Committee C13 | Contact Staff Manager



    WK45479

    1. Rationale

    ASTM C478M currently has two acceptance methods for manhole flat slab tops; section 13.2.2.1 covers acceptance on the basis of a proof-of-design test; section 13.2.2.2 covers acceptance on the basis of a rational design. Currently ASTM C478M has one acceptance method for the 3 types of manhole base slabs following a rational design method. This work item would add a provision to ASTM C478M for acceptance of manhole base slabs based on a proof-of-design test.
