- Scope
4.1 This test method is used to prepare specimens for determining the volumetric and physical properties of compacted asphalt mix.
4.2 This test method is useful for monitoring the density of test specimens during the compaction process. This test method is suited for the laboratory design, field control of asphalt mix, forensics, imaging, and visualization of compacted asphalt mix.
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 standard are cautioned that compliance with Specification D3666 alone does not completely assure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
1.1 This test method covers the compaction of asphalt mix into cylindrical specimens using the Superpave Gyratory Compactor (SGC). This standard also refers to the determination of the relative density of the compacted specimens at any point in the compaction process. Compacted specimens are suitable for volumetric, physical property, and mechanical testing. Smaller specimens may be cut from the compacted cylindrical specimen for specific test specimen geometry requirements. The compaction procedures apply to Laboratory Mix Laboratory Compacted (LMLC) and Plant Mix Laboratory Compacted (PMLC) asphalt mix.
1.2 The values stated in SI units are to be regarded as standard. The value given in degrees for the angle of gyration is a mathematical conversion from the SI units and is provided for information regarding the commonly used unit of degree.
1.3 The text of this test method 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.
