1.1 本试验方法涵盖了通过煅烧测定预制沥青土工膜（PBGMs）中矿物稳定剂含量的程序。 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。 1.4 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 沥青土工膜，无论是由氧化沥青还是聚合物改性沥青制成，都可能含有大量的矿物稳定剂。沥青土工膜中使用的矿物稳定剂的数量对几种物理性质有影响，包括但不限于低温、柔韧性和沥青渗透性（见指南 D6455 获取PBGM属性列表）。

1.1 This test method covers the procedure for the determination of mineral stabilizer content in prefabricated bituminous geomembranes (PBGMs) by calcination. 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 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 Bituminous geomembranes, whether made from oxidized or polymer-modified bitumen, may contain a significant amount of mineral stabilizer. The amount of mineral stabilizer used in a bituminous geomembrane has an effect on several physical properties, including but not limited to cold temperature, flexibility, and asphalt penetration (see Guide D6455 for a list of PBGM properites).
