1.1 本规程涵盖了实验室测试用热再生沥青混合料的制备程序。该程序包括一个迭代的试共混过程，然后制备分批共混物。 1.2 批量共混物可用于广泛评估，例如粘度、渗透性、延展性、老化性能（例如滚动薄膜烘箱或薄膜烘箱测试，或两者（RTFO/TFO））、成分分析、溶解度分析和其他用户选择的测试。 1.3 本规程假设提取具有代表性的再生沥青路面（RAP）样本，并使用试验方法回收老化的粘合剂 D2172/D2172M 和试验方法 D1856 （可通过使用旋转蒸发器对本规程进行修改，该蒸发器在试验的几分钟内进行了广泛评估 第18届太平洋海岸沥青规格会议 2. )或任何其他可接受的测试方法。 1.4 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。 1.5 本标准的文本引用了提供解释材料的注释和脚注。 这些注释和脚注（不包括表和图中的注释和脚注）不应视为本标准的要求。 1.6 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、健康和环境实践，并确定监管限制的适用性。 1.7 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。 ====意义和用途====== 4.1 混合物制备的标准程序对于确保材料质量、规格符合性和程序一致性至关重要。

1.1 This practice covers the procedure for preparation of hot recycled bituminous blends for testing in the laboratory. The procedure involves an iterative trial blend process followed by the preparation of batch blends. 1.2 The batch blends can be used for extensive evaluation such as viscosity, penetration, ductility, aging properties (such as Rolling Thin Film Oven or Thin-Film Oven tests, or both (RTFO/TFO)), composition analysis, solubility analysis, and other user-selected tests. 1.3 This practice assumes that a representative reclaimed asphalt pavement (RAP) sample is extracted and the aged binder recovered using Test Methods D2172/D2172M and Test Method D1856 (this practice may be modified by using a rotary evaporator which is extensively evaluated in the minutes of the 18th Pacific Coast Conference on Asphalt Specifications 2 ) or any other acceptable test method. 1.4 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. 1.5 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. 1.6 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. 1.7 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 A standard procedure for blend preparation is essential to ensure material quality, specification compliance, and procedural uniformity.
