Organization: ASTM
Publication Date: 1 June 2014
Status: active
Page Count: 4
ICS Code (Road construction): 93.080.10
ICS Code (Road construction materials): 93.080.20
scope:

This test method describes a test procedure for determining the density of bituminous concrete by the attenuation of gamma radiation, where the source and detector(s) remain on the surface (Backscatter Method) or the source or detector is placed at a known depth up to 300 mm [12 in.] while the detector or source remains on the surface (Direct Transmission Method).

The density, in mass per unit volume of the material under test, is determined by comparing the detected rate of gamma emissions with previously established calibration data. 

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. 

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. For specific warning statements see Section 6 and Note 5.
