ASTM WK35454

    Revision of C1252 - 06 Standard Test Methods for Uncompacted Void Content of Fine Aggregate (as Influenced by Particle Shape, Surface Texture, and Grading)

    (What is a Work Item?)

    Active Standard: C1252 - 06

    Developed by Subcommittee: C09.20 | Committee C09 | Contact Staff Manager



    WK35454

    1. Rationale

    The manner of strike off affects the accuracy of this test method and should be done as rapidly as possible to prevent consolidation of material in the cylindrical measure (Section 10.2). A strike off guide has been shown to improve the accuracy and consistency of test results, and members present at the June 2011 committee meeting recommended that a strike off guide be mandatory for this test procedure.
