    Revision of D4506 - 13e1 Standard Test Method for Determining In Situ Modulus of Deformation of Rock Mass Using Radial Jacking Test

    (What is a Work Item?)

    This standard is rapidly reaching the end of the eight-year and needs to be reapproved. Other than revising for any new caveats, format updates, and D18.91 reviews not much else is foreseen. However, new and younger members that have joined since this standard was last approved may find things that were missed or need to be updated. However, this test is very expensive, also in ISRM suggested methods, and maybe not done much or any more and maybe should be considered for withdrawal.
