    (What is a Work Item?)

    Active Standard: D2487 - 11

    Developed by Subcommittee: D18.07 | Committee D18 | Contact Staff Manager


    1. Rationale

    The test methods used to determine the soil classification needs to be specified in Section 9.8. Also, the significant digits presented in the calculation of the coefficient of uniformity (Cu) and the coefficient of curvature (Cc) will be made consistent.
