Stone Mastic Asphalt

Stone mastic asphalt (SMA) was originally developed in Germany in the 1960s as a durable road surfacing to resist wear from studded tyres. SMA is designed to have a large percentage of coarse aggregate with stone-on-stone contact, with the remaining voids partially filled with mastic comprising fine aggregate, filler, fibre and bituminous binder.

Stone mastic asphalt (SMA) is a stone-on-stone like skeletal structure of gap graded aggregate, bonded together by mastic, which actually is higher binder content, filler and fiber to reduce the binder drain. This structure improves the strength and the performance of SMA even higher than the dense graded and open graded asphalt mixtures.
