The AASHTO R 71-16 (2020) standard provides guidelines for the sampling and amount of testing of hydraulic cement. This standard is applicable once the cement has been manufactured and is ready for sale in the market. It replaces the previous designation of "test method T 127". The purpose of this standard is to ensure that proper quality control measures are in place for hydraulic cement before it is commercially available. By following the procedures outlined in this standard, manufacturers and sellers can confidently determine the quality and performance of their cement products to meet industry standards and customer requirements. The standard covers the sampling process as well as the specific amount of testing required to assess the cement's quality and properties.
