1.1 本规范涵盖了用于路面施工的沥青粘合剂。 注1: 对于60℃时按粘度分级的沥青粘合剂 °C，见规范 D3381/D3381M . 性能分级沥青结合料见规范 D6373 . 1.2 本规范涵盖以下渗透等级: 40–50, 120–150，以及 60–70, 200–300 85–100, 1.3 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）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》中确立的国际公认标准化原则制定的。

1.1 This specification covers asphalt binder for use in the construction of pavements. Note 1: For asphalt binders graded by viscosity at 60 °C, see Specification D3381/D3381M . For performance-graded asphalt binder, see Specification D6373 . 1.2 This specification covers the following penetration grades: 40–50, 120–150, and 60–70, 200–300 85–100, 1.3 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. 1.4 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.
