ASTM D8079-16 - 1.12.2016
 
Significance and Use

5.1 Asphalt slabs compacted with the rolling compactor can be used to obtain specimens for further testing, including bulk specific gravity following Test Methods D1188, D2726, and D6752, fatigue performance characteristics following Test Method D7460 or AASHTO T 321, and Hamburg wheel-track testing following AASHTO T 324.

5.2 Specimens to perform other standard tests could also be obtained, as long as their volume is contained within the volume of a slab.

Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this practice are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors following the suggestions of Specification D3666 or some similar acceptable guideline that provides a means of evaluating and controlling some of those factors.

 
1. Scope

1.1 This practice covers the fabrication of slabs of asphalt mix using an automated laboratory rolling compactor (RC). Compacted specimens are suitable for volumetric and physical property testing. This 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.

1.3 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.

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.
