Geogrids for Area-wide Repairs

GlasGrid TF

Self-adhesive fibreglass asphalt reinforcement with built-in Tack Film for area-wide repairs of flat surfaces

Read full description >

Product Overview

Self-adhesive geogrid and tack coat in one – the ADFORS GlasGrid TF® (Tack Film).

Tack coats are required for applying the pavement layers. Without spraying, the surfaces will not bond and may crack. Tack coating also presents a number of problems. It is difficult to achieve a correct and even distribution; the splitting time prolongs the construction of the roads and the joint spraying can easily run off on a clean part of the road.

Saint-Gobain ADFORS has developed the ADFORS GlasGrid TF (Tack Film) fibreglass geogrid with a film that replaces the tack coat function, without the usual problems during the use of conventional bonding spray, which guarantees faster repair of asphalt layers and less emissions during installation. The geogrid is easy to apply thanks to the self-adhesive layer.

The ADFORS GlasGrid TF reinforcing geogrid extends the lifespan of roads by up to 300% and saves up to 50% on investment costs associated with maintenance.

Product benefits include:

  • quick and efficient installation due to self-adhesive backing
  • reduced curing time for faster paving construction
  • no damage during application and compaction
  • strong durability to traffic of construction trucks
  • excellent asphalt layers bonding
  • perfect milling performance
  • measured unlimited recyclability & enhanced properties in Reclaimed Asphalt Pavement (RAP)
  • fewer emissions during installation

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.
