Overview

The GlasGrid® asphalt reinforcement system resists the migration of reflective cracks and increases the fatigue life of overlays. When 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.

For road construction projects that require a moisture barrier, Tensar also offers the GlasGrid CG (Compogrid) system. Incorporating a lightweight, polypropylene fabric on the back of the main grid component, the GlasGrid CG system provides additional pavement protection on both new construction and pavement rehabilitation projects.

GlasGrid® is a U.S. registered trademark of Saint-Gobain ADFORS. Other foreign trademarks also apply.

SKUs

The GlasGrid system comes in eight SKUs: CG50, CG100, 8501, 8511, 8502, 8512, and 8550.

Easy Installation in Any Climate

The GlasGrid system can be easily installed without specialized equipment or labor. With its pressure-activated adhesive coating on the underside, it's also one of the fastest interlayer systems to install; up to 25,000 square yards of grid can be placed in one day with a standard laydown unit. Installation readily adapts to local weather conditions or unique construction requirements. From desert environments to near-arctic conditions, the GlasGrid system is effective in a wide range of geographical areas and climates.

Fully Millable and Recyclable

Unlike other interlayer systems, the GlasGrid system is easily broken up by conventional milling equipment and reusable in other road projects as recycled asphalt pavement (RAP). Its main component is silica, a natural substance that is environmentally friendly.

A Trusted, Tested Solution

The use of asphalt reinforcement interlayers for preventing reflective cracking has been extensively studied over the last 40 years. Several research projects have quantified the benefits of the GlasGrid system and helped to define its areas of application.
