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.

Easily Installed, Durable 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 installed; 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.

The GlasGrid System is durable as well, effective in a wide range of geographical areas and climates – from desert environments to near-arctic conditions.

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.
