This test method describes the workability measurement of hydraulic-cement concrete in a slip formed paving applications, both in the laboratory and in the field. The values stated in either inch-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. The text of this standard references notes and endnotes that provide explanatory information. These notes and footnotes shall not be considered as requirements of this standard.
