Geogrids for Special Repairs

GlasGrid Mastic

Fibreglass asphalt reinforcement for special repairs with mastic asphalt

Read full description >

Product Overview

ADFORS GlasGrid® Mastic is a fiberglass geogrid with high tensile strength and mesh stiffness thanks to the coating of glass fibres with a patented modified polymer. The polymer coating also protects the fibres from damage and allows optimal bonding of the layers. ADFORS GlasGrid Mastic is a specially developed geogrid for surface repairs covered with mastic asphalt.

The ADFORS GlasGrid Mastic reinforcing geogrid extends the life of asphalt pavement by up to 300% and saves up to 50% on investment costs associated with maintenance.

Product benefits include:

  • quick and efficient installation
  • elimination of mastic asphalt spilling during the hardening process
  • protection against micro-cracks in mastic asphalt
  • excellent milling properties
  • unlimited recyclability and enhanced properties of Reclaimed Asphalt Pavement (RAP)

FAQs on this product

Do you also offer pavement reinforcement application?

In some countries we have partners offering our products for roads and airports as well. For more information please contact our Sales Manager or customer service listed in the contacts section - select Asphalt Reinforcement.

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 - select Asphalt reinforcement.

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 elimination, 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.

For what type of road are GlasGrids suitable?

ADFORS GlasGrid geogrids are suitable for application on all road categories of flexible pavements.
