This specification covers the design of stone matrix asphalt (SMA) using the Superpave gyratory compactor (SGC). The SMA design is based on the volumetric properties of the SMA in terms of air voids (Va), the voids in mineral aggregate (VMA), and the presence of stone-on-stone contact.
This standard specifies minimum quality requirements for asphalt binder, aggregate, mineral filler, and stabilizing additives for SMA mixture designs.
This standard was formerly designated as AASHTO Provisional Standard MP 8.
