1.1 本规程涵盖了一个实验室程序，通过该程序可以估计不同粗骨料的抛光程度。 1.2 以英寸磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。关于筛网，根据规范 E11 :“以国际单位表示的数值应被视为钢丝布开口尺寸和钢丝布中使用的钢丝直径的标准值。”当参考筛网尺寸时，提供交替的英寸磅名称以供参考，并将其括在括号中。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 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====== 4.1 该实践模拟了车辆交通对沥青路面中使用的粗骨料的抛光作用。 4.2 确定抛光值，该抛光值可用于对粗集料进行评级或分类，以确定其在交通条件下抵抗抛光的能力。 注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。符合规范标准的机构 D3666 通常被认为能够胜任和客观的测试、取样、检查等。本标准的用户应注意遵守规范 D3666 单独使用并不能完全确保可靠的结果。可靠的结果取决于许多因素:遵循规范的建议 D3666 或类似的可接受指南提供了评估和控制其中一些因素的手段。

1.1 This practice covers a laboratory procedure by which an estimate may be made of the extent to which different coarse aggregates may polish. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Regarding sieves, per Specification E11 : “The values stated in SI units shall be considered standard for the dimensions of the wire cloth openings and the diameter of the wires used in the wire cloth.” When sieve mesh sizes are referenced, the alternate inch-pound designations are provided for information purposes and enclosed in parentheses. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 ====== 4.1 This practice simulates the polishing action of vehicular traffic on coarse aggregates used in bituminous pavements. 4.2 A polish value is determined that may be used to rate or classify coarse aggregates for their ability to resist polishing under traffic. Note 1: The quality of the results produced by this standard are dependant upon the competence of the personnel performing the procedure and the capability, calibration, and the maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors: following the suggestions of Specification D3666 or similar acceptable guideline provides a means of evaluating and controlling some of those factors.
