1.1本试验方法包括测量因水对含有沥青水泥的压实沥青混合料的作用而导致的抗压强度损失。通过比较新模制和固化试样的抗压强度与在规定条件下浸入水中的重复试样的抗压强度，获得抗压强度降低的数值指标。 1.2 单位 — 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法可用作压实沥青骨料混合物的水分敏感性指标。 笔记 1-本标准产生的结果的质量取决于执行程序的人员的能力以及所用设备的能力、校准和维护。符合标准实践标准的机构通常被认为能够胜任和客观的测试/采样/检查等。本标准的用户应注意，仅遵守标准并不能完全确保可靠的结果。可靠的结果取决于许多因素；遵循或一些类似的可接受准则的建议提供了一种评估和控制其中一些因素的方法。

1.1 This test method covers measurement of the loss of compressive strength resulting from the action of water on compacted bituminous mixtures containing asphalt cement. A numerical index of reduced compressive strength is obtained by comparing the compressive strength of freshly molded and cured specimens with the compressive strength of duplicate specimens that have been immersed in water under prescribed conditions. 1.2 Units — The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method is useful as an indicator of the susceptibility to moisture of compacted bitumen-aggregate mixtures. Note 1—The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Standard Practice are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
