: Once the asphalt is burned off, the remaining heated aggregate can often be used for sieve analysis (ASTM C136) to check the gradation of the mix.
: Eliminates the need for chlorinated solvents like trichloroethylene, making it a "greener" and safer laboratory procedure for technicians. astm d6307 pdf
The standard recommends determining the correction factor for each unique aggregate blend. Additionally, recalibration should be performed whenever: : Once the asphalt is burned off, the
The correction factor (CF) is determined by testing a sample of uncoated, dry aggregate of the same gradation. Ignite it exactly as you would a regular sample. The loss in aggregate mass is the correction factor: Free, legally distributed PDFs of active ASTM standards
