GlasGrid® a new fiber glass grid structure that was found to reinforce the overlay above the grid and by absorbing the strain at the crack. This technology delays the crack from propagating upward and through to the top of the new asphalt overlay.

Pound for Pound Stronger than Steel GlasGrid® is

• A high strength, fiber glass geogrid that reduces stress in asphalt overlays.
• Has a unique self-adhesive system which makes it very easy to install.
• Paves the way to lower maintenance costs.

How GlasGrid Works Reinforces asphalt concrete overlays in pavement construction. The GlasGrid® layer is "sandwiched" in between the levelling and surface course of asphalt. The fiber glass grid is designed to turn crack stresses horizontally and dissipate the crack stress. Helps retard cracks from reflecting through a new asphalt overlay.

Road Preparation
Complete all crack sealing, pothole filling, base repairs, and installation of levelling course.

Road Surface Conditions for Placing GlasGrid®
Surface must be smooth, clean and dust free, between 40ºF and 140ºF. Minimum 3/4" level up course must be applied 24 hours prior to installing GlasGrid®.

Placement of GlasGrid®
Longitudinal overlap must be 1-2 inches and the transverse overlap must be 3-6 inches. Once the GlasGrid® has been placed, it must be rolled with a rubber-tire roller to ensure a good bonding between the GlasGrid® and the road surface.

Paving Over GlasGrid®
The surface course of asphalt can be placed immediately after the GlasGrid® is installed. There are no disruptions or delays to normal paving operations. Minimum 1 1/2" compacted overlay is required.
