ASTM WK69565

    Revision of C1645 - 16 Standard Test Method for Freeze-thaw and De-icing Salt Durability of Solid Concrete Interlocking Paving Units

    (What is a Work Item?)

    Active Standard: C1645 - 19

    Developed by Subcommittee: C15.03 | Committee C15 | Contact Staff Manager



    WK69565


    Keywords

    freeze-thaw durability; interlocking concrete pavers;;

    Rationale

    C1645 requires a drying oven temperature maintained at 100 - 115C. Other standards for testing (ASTM C140, aggregate testing standards) require ovens to maintain 110 5C. This ballot proposes modifications to C1645 to make the oven temperature consistent with other standards. This will help to simplify requirements for labs using multiple methods. The proposed language is consistent with ASTM C140.
