This CF is then subtracted from the apparent binder content of the asphalt mixture sample.
Once the asphalt is burned off, the remaining aggregate can be used for sieve analysis to check particle size distribution, though some degradation may occur during heating. astm d6307 pdf
A major benefit of this method is that the remaining aggregate can often be reused for sieve analysis (gradation testing), though some degradation may occur due to the high heat. This CF is then subtracted from the apparent
ASTM D6307-19 defines the ignition method for determining asphalt binder content in hot-mix asphalt (HMA) by burning off the asphalt at approximately 538°C in a specialized furnace. This,, environmentally friendly procedure uses an internal balance to monitor weight loss, providing a precise, efficient alternative to traditional solvent extraction methods. The official standard can be purchased directly from the ASTM International official website . ASTM D6307-19 defines the ignition method for determining
