(Test Method)Standard Test Method for Moisture or Volatile Distillates in Asphalt Mixtures
Standard Test Method for Moisture or Volatile Distillates in Asphalt Mixtures
SIGNIFICANCE AND USE
3.1 This test method is used for determining either the amount of moisture or the amount of volatile petroleum distillates in asphalt mixtures.
3.2 Applicable standards are those in which measurements or calibrations are made, samples are procured, or products are selected.3
SCOPE
1.1 This test method covers the determination, by direct measurement, of moisture or volatile fractions of the asphalt in asphalt mixtures.
1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
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 and health 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.
