This method is widely preferred over older solvent-extraction methods (like ASTM D2172) because it is faster, more environmentally friendly (no hazardous solvents), and highly accurate when properly calibrated.
⚠️ Be cautious of “free PDF” sites like academia.edu, scribd.com, or unknown document repositories. These often host the 2002 or 2008 versions of ASTM D6307, which are obsolete. Using an outdated method could invalidate your test results. astm d6307 pdf
ASTM D6307 is the standard test method for determining the asphalt binder content of hot-mix asphalt (HMA) by burning it off in a furnace at approximately 540°C. The procedure provides a safe, solvent-free alternative for quality control and allows for subsequent sieve analysis on the remaining aggregate. Purchase the official standard at ASTM International more environmentally friendly (no hazardous solvents)
