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. D6307 Standard Test Method for Asphalt Content of
