About This Item

 

Full Description

This standard practice 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), voids in the mineral aggregate (VMA), and the presence of stone-on-stone contact.
