SMA

Stone Mastic Asphalt

Increasing traffic volumes, higher axle loads, changes in our climate − the challenges road construction experts around the globe have to face.

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 performance fiber pellets. The low void content makes the compacted layer practically impermeable to water.


  • Safe
  • Versatile
  • Durable 
  • Economic

With these features, SMA fulfils all the requirements of modern infrastructure − offering its benefits to road users, local authorities and the asphalt industry alike.
