ASTM WK47057

    Revision of C1319 - 11 Standard Specification for Concrete Grid Paving Units

    (What is a Work Item?)

    Active Standard: C1319 - 11

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



    WK47057

    1. Rationale

    This change proposes to add an annual testing frequency for compressive strength, absorption, density, and dimensional tolerances. The proposed time frame relates to the production date, since there are some specialty units that are produced, and may remain in inventory for over 1 year. Anchoring the time frame from production date does not trigger additional testing on these specialty units if they are not manufactured at least annually. Additionally, this ballot proposes to add language so that a change in configuration or dimension does not trigger additional testing. This language mirrors that already in ASTM C140 for lot, and allows for recognition that for many concrete masonry units, several configurations may be produced from the same batch, at the same time. Testing on all configurations is not necessary, so long as the other variables (mix design, materials, production and curing methods) do not change. NOTE identical language was added to ASTM C90 in a previous balloting cycle, so this change harmonizes C1319 and C90. Additionally, it is not necessary to maintain the testing exemption on compressive strength testing since ASTM C140 contains specific procedures for grid paving units, and this testing detail is handled in that standard.
