1.1本试验方法包括通过直接测量测定冷拌沥青混合料在500°F（260°C）环境温度下的挥发性馏出物分数。 1.2由于本试验方法仅用于研究目的或信息，因此尚未制定本标准的精度和偏差声明。因此，本标准不应用于验收或拒收用于采购目的的材料。 1.3以英寸-磅为单位的数值应视为标准值。 括号中给出的国际单位仅供参考。 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法用于测定冷拌沥青混合料中特定温度的挥发性馏分的量。

1.1 This test method covers the determination, by direct measurement, of the ambient to 500°F (260°C) volatile distillate fraction of cold mix asphalt mixtures. 1.2 A precision and bias statement for the Standard has not been developed since this test method is used for research purposes or information only. Therefore this Standard should not be used for acceptance or rejection of a material for purchasing purposes. 1.3 The values stated in inch-pound units are to be regarded as the standard. The SI units given in parentheses are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method is used for determining the amount of a temperature specific volatile distillate fraction in cold mix asphalt mixtures.
