Product Description

GlasGrid® Asphalt Reinforcement System
The GlasGrid® Asphalt Reinforcement System is composed of fiberglass strands coated with an elastomeric polymer and formed into a grid structure. Each strand has a remarkably high tensile strength and high modulus of elasticity; this is particularly important as asphalt concrete typically cracks at low strains.

When the GlasGrid System is sandwiched between the leveling course and the surface course in an asphalt overlay, it becomes the hidden strength in the road, turning vertical crack stresses horizontally to effectively dissipate them.

GlasGrid® CG (Compogrid) System: Asphalt Reinforcement with a Moisture Barrier
For road construction projects that require a moisture barrier, Tensar offers the GlasGrid® CG (Compogrid) System. Incorporating a lightweight, polypropylene fabric on the back of the main grid component, GlasGrid CG provides additional pavement protection on both new construction and pavement rehabilitation projects.
