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.
With these features, SMA fulfils all the requirements of modern infrastructure − offering its benefits to road users, local authorities and the asphalt industry alike.
The perfect solution to meet the challenges of modern roads - mobility at its best, all around the world.
Bituminized fibrous pellets VIATOP®
have a beneficial effect on fatigue and aging behavior due to the thicker binder films!
