Standard Test Methods for
Asphalt Content of Bituminous Mixtures by the Nuclear

This standard is issued under the fixed designation D 4125; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 These test methods cover the procedures for determining the asphalt content of samples of uncompacted bituminous
mixtures (Test Method A), and laboratory compacted
specimens of bituminous mixtures (Test Method B) by examining a test sample with an apparatus that utilizes neutron
thermalization techniques.

1.2 The values expressed in SI units are regarded as the
standard. The inch-pound equivalents may be approximate.

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 and health practices and determine the applicability of regulatory limitations prior to use. See Section 6 and
Note 1, Note 4, and Note 6, for specific hazards.
