Yes, but with caution. The ignition method burns off the aged binder in RAP as well as the virgin binder. The standard requires that you account for the residual binder content of the RAP through a separate extraction or ignition test on the RAP alone.
If you need help implementing this standard in your laboratory, let me know:
Aggregates lose a small amount of weight when exposed to extreme heat due to the loss of chemically bound water or minor mineral degradation. Therefore, ASTM D6307 requires a (or correction factor) for each specific aggregate blend. astm d6307 pdf
Once you have the standard, invest time in properly calibrating your equipment, training your staff, and establishing a routine for correction factor verification. With ASTM D6307 as part of your quality system, you can confidently produce asphalt mixes that meet specifications, reduce waste, and build longer-lasting roads.
The sample is placed in the furnace and heated. The ignition oven burns off the asphalt binder. The test concludes when no further mass loss is detected over a 3-minute period. 4. Cooling and Final Weight Yes, but with caution
The asphalt mixture sample is warmed in a standard oven until it is soft enough to quarter and separate. It must be dried to a constant mass to ensure any moisture present does not register as lost binder during the ignition phase. 2. Establishing a Correction Factor
