External scales for precise manual weighing before and after the burn.

The asphalt pavement industry relies heavily on precise quality control to ensure long-lasting roads, highways, and runways. One of the most critical parameters in asphalt production is the asphalt binder content. Too much binder leads to rutting and flushing; too little binder results in cracking and premature raveling.

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.

The basket is placed in the furnace. The internal software tracks the mass loss. The test automatically terminates when the mass change drops below a specified limit (typically 0.01% for three consecutive minutes).
