    (What is a Work Item?)

    Active Standard: C478 - 15

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


    1. Rationale

    ASTM C478 currently has two acceptance methods for manhole flat slab tops; section covers acceptance on the basis of proof-of-design test; section covers acceptance on the basis of rational design. Currently, ASTM C478 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 C478 for acceptance of manhole base slabs based on a proof-of-design test.
