Award winning Superflex™ can be used in base or binder course layer and combines the properties of high fatigue resistance with excellent deformation resistance. It is suited for use in a wide variety of applications and particularly where cracking is a problem.

Features:

  • Excellent crack resisting properties means Superflex is the ideal material when overlaying concrete.
  • Excels in both deformation resistance and fatigue life over conventional mixtures.
  • Allows early and temporary trafficking where site restrictions prevent the application of a surface course prior to the removal of traffic management.
  • Impermeable, keeping out the unwanted action of trapped water.
  • High fatigue resistance resulting in longevity and therefore reduced costs.
  • Elastomeric polymer modified binders.

Applications:

  • All highways applications from lightly trafficked residential to major heavily trafficked motorways.
  • Commercial and industrial areas.
