AASHTO M 323-22

This specification for Superpave volumetric mix design uses aggregate and mixture properties to produce job-mix formulas for asphalt mixtures. It includes the original Superpave design method based on four percent air voids and the Superpave5 design method based on five percent air voids.

This standard specifies minimum quality requirements for binder, aggregate, and asphalt mixtures for Superpave volumetric mix designs.
