Stone Matrix Asphalt

Stone Matrix Asphalt (SMA) - is a tough, stable, rut resistant mixture that relies on stone-to-stone contract for its strength and a rich mortar binder for its durability. Theoretical maximum density (TMD, also called "Rice density") - The theoretical maximum density of an HMA if it contained zero air voids.

May 31, 2019  Generally a standard asphalt mix is called Hot Mix Asphalt (HMA) or dense graded asphalt. The roadway is ground down and paved over. The HMA, made up of a mix of sand, oil and aggregate stone between 3/8- to ½-inch in size, is poured on the road. It gets heated, pressed down and rolled into that smooth surface we all know and love.

Mix Types – Pavement Interactive

Stone matrix asphalt (SMA), sometimes called stone mastic asphalt, is a gap-graded HMA originally developed in Europe to maximize rutting resistance and durability. The mix design goal is to create stone-on-stone contact within the mixture. Since aggregates do not deform as much as asphalt binder under load, this stone-on-stone contact greatly ...

Stone Matrix Asphalt (SMA) mixtures for six combinations of TWPD load and speed were tested. The combination with the lowest load (91 lbs.) and highest speed (60 rpm) was found to wear the HMA surface more than other combinations. In Phase II, the rate of friction change was evaluated by varying the amount of friction aggregate in a mixture.
