ASTM standards are updated periodically. As of this writing, the current version of D6307 is (released 2019). However, ASTM frequently issues redlines or revisions. To ensure you always have the latest version:
The asphalt mixture sample is heated and split to the appropriate test size based on the maximum aggregate size.
While it is tempting to search for a free download, the risks of using an unauthorized, outdated copy far outweigh the savings. Purchase the official PDF from ASTM International or an authorized reseller to ensure you have the most current, legally compliant version.
Corrected Asphalt Content (%)=Raw Binder Loss (%)−Aggregate Correction Factor (%)Corrected Asphalt Content (%) equals Raw Binder Loss (%) minus Aggregate Correction Factor (%) 5. Why the ASTM D6307 PDF is Essential for QA/QC astm d6307 pdf
The standard recommends determining the correction factor for each unique aggregate blend. Additionally, recalibration should be performed whenever:
ASTM D6307-19 defines the standard ignition method for determining asphalt binder content in hot-mix asphalt by heating samples to approximately 540°C to measure weight loss. The standard covers both automatic furnace procedures and manual, external weighing methods, while requiring a calibration factor to account for aggregate degradation.

Statistical limits on acceptable variations between multi-laboratory and single-operator test results.
For preheating and drying asphalt samples to a constant mass before testing. To ensure you always have the latest version:
Different aggregates undergo varying degrees of mass loss when exposed to extreme heat (due to the breakdown of minerals like carbonates). Therefore, a must be established for each specific aggregate blend before testing production mixes. Step 3: Ignition
Quality Assurance (QA) and Quality Control (QC) programs in civil engineering rely heavily on this standard for several reasons:
