Stone Mastic Asphalt (SMA) - Boral

Stone Mastic Asphalt is a thin asphalt surfacing mix, which has very good rut resistance properties and excellent durability compared to standard asphalt. It can also be used as a base course mix. While it is primarily used for heavily trafficked roads and is the preferred surfacing in some countries, SMA can be used for all types of pavements.

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.

JRS - SMA - Stone Mastic Asphalt

Stone Mastic Asphalt (SMA) has shown its outstanding performance on a variety of road surfaces throughout the world for more than 40 years − making SMA one of the most popular surfaces courses used. SMA is based on the concept of a self-supporting stone skeleton, with a thick mastic and high binder content. This is made possible by using high ...


The current concept of Stone Mastic Asphalt (SMA) or "Split Mastic Asphalt" was developed in Germany in the mid-sixties and introduced in Canada in 1991. Stone Mastic Asphalt is a gap graded bituminous mixture with a high content of chippings which constitute an interlocking mineral skeleton to resist permanent deformation.
