ASTM D6925-23 pdf free download – Standard Test Method For Preparation And Determination Of The Relative Density Of Asphalt Mix Specimens By Means Of The Superpave Gyratory Compactor.
This test method outlines the procedure for compacting an asphalt mix into cylindrical specimens utilizing the Superpave Gyratory Compactor (SGC). It also includes guidelines for determining the relative density of the compacted specimens throughout the compaction process. The resulting compacted specimens are suitable for various tests related to volumetric analysis, physical properties, and mechanical performance. For specific testing requirements, smaller specimens can be extracted from the compacted cylindrical samples. The compaction procedures are applicable to both Laboratory Mixed Laboratory Compacted (LMLC) and Plant Mixed Laboratory Compacted (PMLC) asphalt mixes.
Values presented in SI units are considered the standard. Additional values expressed in degrees for the angle of gyration, revolutions per minute, and hardness are mathematical conversions from SI units and are included for reference to commonly used units such as degrees, rotations per minute, and Rockwell hardness, respectively.
This test method includes references to notes and footnotes that provide supplementary information. It is important to note that these notes and footnotes (excluding those found in tables and figures) are not considered mandatory requirements of the standard.
