The raw percentage of weight loss is calculated. The pre-determined aggregate correction factor is subtracted from this raw value to yield the final, corrected asphalt binder content percentage.

– full title: Standard Test Method for Asphalt Binder Content of Asphalt Mixture by Ignition Method – describes a procedure for determining the asphalt binder content in a sample of asphalt mixture. The test works by heating a sample to a high temperature (typically around 538°C or 1000°F) in a furnace to ignite and burn off the asphalt binder, leaving behind the aggregate. The difference in mass before and after ignition gives the asphalt binder content.

The primary feature of is the determination of asphalt content in paving mixtures using an ignition furnace . This standard provides a faster, solvent-free alternative to traditional chemical extraction methods by burning off the asphalt cement at high temperatures (typically ) and calculating the mass loss.

ASTM D6307 provides detailed instructions on sample size based on nominal maximum aggregate size. For example, a mixture with a 25 mm (1 in.) NMAS requires a larger sample mass than a 9.5 mm (3/8 in.) mixture to ensure representativeness.

While the official standard must be purchased to view the full details, its structure typically includes these key sections: The test works by heating a sample to
