The asphalt binder content is calculated as the difference between the initial mass and the residual mass of the aggregate, adjusted for a specific calibration factor and moisture content. Key Technical Details astm d6307 pdf
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. Many quality control plans require that testing personnel
