Asphalt road pavements are defined as asphalt layers built bound over a granular base. Due to this, the total pavement structure deflects due to traffic loads, thus these types of pavements are known as flexible pavements. A flexible pavement structure is composed of various layers of materials.

Item 443 Stone Matrix Asphalt Concrete may also be considered but not for small quantity applications. For all high stress locations where rutting is evident, pavement planing should be specified to remove all deformed material. For flexible pavement, planing should be specified to the bottom of the material responsible for the rutting.

Stone matrix asphalt (SMA), also called stone mastic asphalt, is a durable and rut-resistant asphalt mixture that relies on stone-on-stone contact to offer strength and a rich mortar binder to provide durability (Hughes 1999). SMA was introduced into the United States in the early 1990s

The slurry mixture contains asphalt emulsion that breaks onto the pavement surface through heterogeneous or homogenous flocculation. The asphalt particles coalesce into films, creating a cohesive mixture. The mixture then cures, by loss of water, into a hardwearing, dense-graded asphalt/aggregate mixture that is bonded to the existing pavement.

Stone matrix asphalt (SMA) is a gap-graded hot mix asphalt with a high percentage of coarse aggregate and a high asphalt content. SMA is the typical gap-graded mixture used in Virginia that is intended to maximize rutting resistance and durability with a stable stone-on-stone skeleton held together by a rich mixture of asphalt binder.
