Tuffpave®

Tuffpave is an approved, polymer-modified thin surfacing system that can be laid by any approved licensed laying contractor. It uses the same distinctive ingredients as Tuffgrip, and performs to the same high standards on noise and spray reduction, and skid resistance, while delivering excellent ride quality.

It has been designed as a gap-graded mixture containing a high percentage of coarse aggregate bound by the polymer modified binder. The coarse aggregate provides an interlocked framework giving excellent resistance to deformation while the polymer modified binder ensures maximum durability. The mix design and choice of aggregate size provide a texture depth that is retained throughout the life of the surfacing, and gives significant reduction in noise over more traditional surfacings, such as Hot Rolled Asphalt (HRA) and concrete.

Benefits

The main advantages of Tuffpave when used as a maintenance treatment, either as inlay or overlay or as a surface course for new construction, are:

  • Restores texture and skid resistance
  • Strong and durable
  • Excellent resistance to deformation
  • Enhanced ride quality
  • Excellent noise reduction
  • Excellent spray reduction
  • Provided as a system – Hanson manage the approval process

Applications

  • Major highways

  • Major paved areas
  • Local Authority network

The Tuffpave range includes:

  • Tuffdrive- a durable material for residential driveways.
  • Tuffdrain- essentially developed for use in Sustainable Urban Drainage Systems and filter drains at the edge of motorways and other major roads
  • Tufflex- a polymer-modified binder/surface course with excellent load spreading ability
