ASTM D4125/D4125M-10

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

SIGNIFICANCE AND USE
These test methods are useful as a rapid, nondestructive technique for determination of asphalt content of bituminous mixtures.
These test methods are suitable for quality control and acceptance testing for construction and for research and development applications. The test method is used for determination of asphalt content only as it does not provide extracted aggregate for gradation analysis.
The non-destructive nature of the test allows repetitive measurements to be made on a single test sample for statistical analysis of test data.
These test methods determine the asphalt content of a test sample by comparing the measured asphalt content with previously established calibration data.
The asphalt content of a material expressed as a percentage, is the ratio of the mass of asphalt in a given mass of material to the total mass of the sample or to the mass of the solid material particles.
SCOPE
1.1 These test methods cover the procedures for determining the asphalt content of samples of uncompacted bituminous mixtures (Test Method A), and of 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 stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 A precision and bias statement for Method B in this standard has not been developed at this time. Therefore, Method B should not be used for acceptance or rejection of a material for purchasing purposes.
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. See Section 6 and 8.4.2, 8.5.6, and Note 4, for specific hazards.
