Control of Asphalt Cracking

Fatigue and reflective cracking in pavements are typically caused by traffic loading, age hardening or temperature cycling. Conventional remedies have included the application of thicker asphalt overlays – a solution that addresses the problem only at the surface, and for a limited period of time. For each inch of applied overlay, reflective cracks are often assumed to be deterred from reaching the surface for a period of just one year. 


    The GlasGrid® Asphalt Reinforcement System provides an additional means of resisting the migration of reflective cracks in pavement applications, reducing maintenance costs and extending pavement service life by 200% or more. Manufactured by Saint-Gobain ADFORS and distributed exclusively in the Americas by Tensar International, the GlasGrid System has been used on thousands of highways, roadways, parking lots, airport aprons and runways throughout the world. 

    Installed between an asphalt leveling course and the surface course, the GlasGrid System becomes the hidden strength in a road, turning reflective vertical crack stresses horizontally to effectively dissipate them.


    Delay Asphalt Cracking, Extend Pavement Service Life

    Installed between an asphalt leveling course and the surface course, the GlasGrid System becomes the hidden strength in a road, turning reflective vertical crack stresses horizontally to effectively dissipate them.

    The GlasGrid System has addressed reflective cracking caused by:


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