This standard practice for mix design evaluation uses aggregate and mixture properties to produce a hot mix asphalt (HMA) job-mix formula. The mix design is based on the volumetric properties of the HMA in terms of the air voids, voids in the mineral aggregate (VMA), and voids filled with asphalt (VFA).
This standard practice may also be used to provide a preliminary selection of mix parameters as astarting point for mix analysis and performance prediction analyses that primarily use T 320 and T 322.
