Geogrids for Area-wide Repairs

GlasGrid CG

Composite fibreglass asphalt reinforcement with waterproofing function for area-wide repairs of milled surfaces

Read full description >

Product Overview

ADFORS GlasGrid® CG meets the demands of the growing market for reinforcing geogrids with a functional waterproofing membrane. ADFORS GlasGrid CG is a composite material made of a high-strength fibreglass grid and a solid structure coated with a patented elastomeric polymer and from layer of heavy non-woven fabric.

The high strength, high modulus, stiff fibreglass geogrid reduces the potential for thermal and stress-related cracks reflecting through to the surface of a new asphalt overlay. The non-woven fabric with a high absorbency of the tack coat acts as an insulating interlayer. The entire system extends the life of roads up to 3 times and saves up to 50% of investment costs associated with maintenance.

Product benefits include:

  • fast and efficient installation
  • effective waterproofing interlayer
  • no damage during application and compaction
  • resistance to the traffic of construction trucks
  • perfect bonding of asphalt layers

FAQs on this product

Do you also offer geogrid application?

In some countries we have partners offering our products and application as well. For more information please contact our Sales Manager or customer service listed in the contacts section.

Is it possible to receive GlasGrid samples?

We have A4 size samples available. If you are interested, please contact our Sales Manager or customer service listed in the contacts section.

What are the advantages of glass fibers geogrids?

Based on strength/strain ratio, the glass fiber geogrids provide very high ability to resist crack propagation in comparison with geogrids made from different row materials. Glass fiber grids improve the life of an asphalt pavement by 200–300% through reflective crack retardation, limit rutting, bring structural benefit and allow final reuse of interlayer due to recycling of geogrid.

Is GlasGrid millable and recyclable?

Yes, laboratory tests and experience from construction sites confirm that the ADFORS GlasGrid does not show any negative effects during milling and does not affect the depth of milling.  The ADFORG GlasGrid is unlimitedly recyclable and the partial reuse of milled asphalt granulate (including glass fibers) in a new asphalt mixture improves the fatigue behaviour of the recycled asphalt.

Can we use a GlasGrid for airport repairs?

Yes, ADFORS GlasGrid is suitable for airport repairs. It has already been successfully applied at more than 200 airports around the world.
