ASTM D7981-15

5.1 Asphalt prisms compacted with the Shear Box Compactor can be used to obtain specimens for further testing, including bulk specific gravity following Test Methods D6752 and D2726, Dynamic modulus following AASHTO T342, dynamic modulus, flow number, and flow time following AASHTO TP79, and fatigue performance characteristics following AASHTO T321.

5.2 Specimens to perform other standard tests could also be obtained, as long as their volume is contained within the volume of a prism having maximum width, length and height (W×L×H) of 150 mm, 450 mm, and 185 mm, respectively.

1.1 This practice covers the fabrication of prismatic specimens of asphalt mixture using the Shear Box Compactor (SBC). Compacted specimens are suitable for volumetric and physical property testing. This standard practice should not be used for acceptance or rejection of a material or for purchasing purposes.

1.2 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard with exception of degrees (°) where angle is specified.

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.

1.4 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.
