Astm D6307 Pdf May 2026

The ASTM D6307 standard specifies the test method for determining the asphalt content of hot-mix asphalt (HMA) mixtures using the ignition method. This process is a common alternative to solvent extraction methods, which are often more hazardous and time-consuming. Key Features of ASTM D6307

Unlike older solvent-based extraction methods (which use chemicals like trichloroethylene), the ignition method is faster, safer, and more environmentally friendly. The test involves heating a sample of the asphalt mixture in a furnace to a high temperature (typically around 538°C or 1000°F), causing the asphalt binder to burn off, leaving behind the aggregate. The difference in mass before and after ignition represents the asphalt binder content. astm d6307 pdf
