ASTM WK96045
In 2023, C1884 Specification for Concrete Ballast Block was renamed as C1884 Specification for Manufactured Concrete Ballast Units and was revised throughout to consolidate and incorporate the requirements of C1491 Specification for Concrete Roof Pavers into a single standard. In 2024, the testing requirements for the new C1884 were incorporated into a revamped Annex A6. While the requirements for compressive strength coupons work well for the vast majority of concrete ballast units, some units like legacy roof pavers with a relatively thin body and support ribs, have a body thickness of less than 1.5 in. [40 mm]) and do not allow obtaining a coupon that meets the requirement in A6.4.2 (1). This ballot item is proposing adding a note on recommendations on how to test these units that fall outside the current testing requirements.
