ASTM D1461-85(2006)

Standard Test Method for Moisture or Volatile Distillates in Bituminous Paving Mixtures

SIGNIFICANCE AND USE
This test method is used for determining either the amount of moisture or the amount of volatile petroleum distillates in bituminous paving mixtures.
SCOPE
1.1 This test method covers the determination, by direct measurement, of moisture or volatile fractions of the bitumen in bituminous paving mixtures.
1.2 The values stated in SI units are to be regarded as the standard. The values 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.
