Geogrids for Local Repairs

GlasGrid PM

Self-adhesive composite fiberglass asphalt reinforcement patch grid with bitumen layer for local repairs around manhole covers

Read full description >

Product Overview

ADFORS GlasGrid® PM (Patch Manhole) is a fast and safe ring-shaped repair system for repairing surfaces around manhole covers. The geogrid consists of a high-stiffness fiberglass grid, which is coated with a patented polymer layer, non-woven fabric and is provided with a thin layer of modified asphalt for perfectly fixing the geogrid to the milled surface.

This composite geogrid significantly shortens the repair time thanks to the application without the use of a tack coat.

The ADFORS GlasGrid PM repair reinforcement system postpones the formation of reflective cracks by up to 3 times and saves up to 50% on road maintenance costs.

Product benefits include:

  • fast and efficient installation thanks to a self-adhesive asphalt layer and a special shape
  • application without heating
  • does not damage the geogrid during installation and compaction
  • perfect connection of asphalt layers
  • 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.

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.
