1.1 本规程适用于回收主要由半固体或液体沥青基、水和乳化剂组成的乳化沥青残渣。可以用聚合物改性剂对沥青基进行预改性，或者可以通过共研磨或后乳化沥青生产混合将乳胶聚合物改性物掺入乳化沥青中。 1.2 本标准的文本引用了提供解释性材料的注释和脚注。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。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前建立适当的安全、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（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 这种做法可用于获得乳化沥青的残留物。残留物可用于进一步测试。 4.2 由于通常获得约5g的残留物，因此可以进行有限的测试。 注1: 试验方法中描述的流变特性 D7175 和 D7405 是合适的测试方法。正在开发适用于获得的少量残留物的其他测试方法。

1.1 This practice is suitable for recovery of the residue of emulsified asphalts composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent. Asphalt base may be pre-modified with polymeric modifiers or latex polymer modifiers may be incorporated into the emulsified asphalt through co-milling or post emulsified asphalt production blending. 1.2 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. 1.3 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 can be used to obtain residues of emulsified asphalts. The residue may be used for further testing. 4.2 As approximately 5 g of residue is typically obtained, limited testing is possible. Note 1: Rheological characterization as described in Test Methods D7175 and D7405 are suitable test methods. Additional test methods are being developed suited to the small amounts of residue obtained.
