Standard Practice for Recovering Residue from Emulsified Asphalt Using Low-Temperature Evaporative Technique 使用低温蒸发技术从乳化沥青中回收残留物的标准实践
发布日期: 2021-05-01
1.1 本规程涵盖了从乳化沥青中回收残渣的方法,如规范中规定的方法 D977 和 D2397/D2397M 使用类似于路面条件的低温蒸发技术。根据需要,回收的残渣可用于进一步测试。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 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。 1.4 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。 1.5 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====== 3.1 本实施规程中描述的程序用于从乳化沥青中获得残渣,该残渣可用于在动态剪切流变仪等设备中进行进一步测试。该程序的较低蒸发温度提供了非常接近这些材料应用技术的条件。这种做法可用于替代测试方法等恢复技术 D6934 和 D6997 当这些标准中使用的温度会对残留物产生负面影响时。 注1: 本标准产生的结果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 通常认为能够胜任和客观的测试、抽样、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;遵循规范建议 D3666 或一些类似的可接受指南提供了评估和控制其中一些因素的方法。
1.1 This practice covers a method for recovering the residue from emulsified asphalts such as those specified in Specifications D977 and D2397/D2397M using a low-temperature evaporative technique that is similar to pavement conditions. The recovered residue can be used for further testing as required. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 ====== 3.1 The procedure described in this practice is used to obtain a residue from an emulsified asphalt that may be used for further testing in devices such as a dynamic shear rheometer. The lower evaporative temperatures of this procedure provide conditions that are very close to those of application techniques for these materials. This practice could be used in place of recovery techniques such as those of Test Methods D6934 and D6997 , when the temperatures used in those standards would negatively affect the residue. 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 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 some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
