Road Construction


Successful solution with VIATOP® fibres for STONE MASTIC ASPHALT. (SMA)

The benefits

  • High resistance to permanent deformation
  • Excellent skid resistance
  • Reduced waterspray
  • Elimination of aquaplaning
  • Increased visibility of road markings
  • Reduced glare at night from reflections of lights
  • Superior durability
  • Low noise level
  • Decreased life-time-costs

SMA pavements last 20 years and even longer!!!

Adding VIATOP®, a granulate from modified cellulose fibres, to the asphalt mix stabilizes it. Those road surfaces demonstrate an exceptional high resistance to deformation - even in the heaviest traffic - and have an extremely long product life.

The main field of application is the stone mastic construction method (SMA). This is a road bitumen pavement having a special formulation. Based on its qualitative superiority when compared with conventional pavements, VIATOP® reinforced SMA has, in the last 25 years, become the pavement choice No. 1 on European roads. Overseas SMA with JRS fiber is increasingly becoming the standard road pavement.

With other types of asphalt construction methods such as noise-reducing asphalt, thin layer asphalt or asphalt binder courses, our fibers also help to substantially improve the quality and, in doing so, the economy.
