Delay Asphalt Reflective Cracking


Tensar International is the exclusive Americas distributor for the GlasGrid® Pavement Reinforcement System from Saint-Gobain Technical Fabrics. The GlasGrid System is ideal for addressing the rehabilitation challenges of reflective cracking distress on highways, airport aprons, runways and parking lots and dramatically extending pavement life.

Industry-Proven Track Record
: Over twenty years of successful use in asphalt overlays demonstrate that GlasGrid products are an effective solution for mitigating reflective cracking caused by conditions such as:

  •   Concrete pavement longitudinal and transverse joints
  •   Thermal loads
  •   Lane widening
  •   Cement-treated or stabilized layer shrinkage cracks
  •   Block cracks
  •   Asphalt construction joints

Strength and Fast Installation
: The GlasGrid System capitalizes on the high tensile stiffness of fiberglass. Its grid configuration features fiberglass strands coated with an elastomeric polymer. Each strand has a remarkably high modulus of elasticity that makes GlasGrid stronger than steel by weight.

A pressure-activated adhesive coating on the underside of the grid makes GlasGrid one of the fastest-to-install interlayer systems.

GlasGrid products installed within an asphalt layer can be milled with traditional equipment and reused in road projects as a recycled asphalt product.

New GlasGrid TF Delivers Improved Installaion and Better Bonding: 
For 2010, Saint-Gobain introduces GlasGrid TF, which includes all the advantages of regular GlasGrid plus the added advantage of a dry polymer tack film. This innovative interlayer uses an integral 100% polymer tack film to eliminate the need for a traditional spray-applied tack coat.

GlasGrid TF delivers a stronger bond that not only improves reflective crack resistance but now also withstands overlay fatigue five times longer than an unreinforced overlay (based on initial testing).  Efficient installation is another benefit of GlasGrid TF since there are no emulsion spray trucks, curing delays, variability in tack application rate, or prohibition against wheel contaminated asphalt trucks driving on the roadway during construction.
