1.1 本规程涵盖了一种快速程序，用于直观观察未压实的沥青涂层骨料混合料因沸水作用而失去的粘附力。 1.2 单位-- 以国际单位制或英寸-磅单位表示的值应单独视为标准值。每个系统中所述的值可能不是完全等效的；因此，每个系统都应独立使用。将两个系统的值结合起来可能会导致不符合标准。 1.3 本标准的文本引用了提供解释性材料的注释和脚注。这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为本标准的要求。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 5.1 这种做法可以作为沥青相对敏感性的指标- 涂层骨料与水的关系，但不应作为现场性能的衡量标准，因为这种相关性尚未建立。如果表明因水而失去附着力，则应通过其他程序进行测试，以进一步评估混合物。 5.2 业主机构不应将此做法用于验收/拒收。

1.1 This practice covers a rapid procedure for visually observing the loss of adhesion in uncompacted asphalt-coated aggregate mixtures due to the action of boiling water. 1.2 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be 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. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This practice is useful as an indicator of the relative susceptibility of asphalt-coated aggregate to water, but should not be used as a measure of field performance because such correlation has not been established. If loss of adhesion due to water is indicated, testing by other procedures should be conducted to further evaluate the mixture. 5.2 This practice should not be used for acceptance/rejection by owner agencies.
