Glasgrid Pavement Reinforcement Geogrid-Asphalt Geogrid

GlasGrid pavement reinforcement geogrids are a high strength self-adhesive reinforcement grid designed to control reflective cracking in asphalt concrete overlays on roads, freeways, bridges and car parks.

GlasGrid reduces both thermal and stress-related cracking. Its self-adhesive application allows for quick installation and the fibreglass components account for its exceptional performance.

The fiberglass grid is “sandwiched” between the levelling and surface courses of asphalt, and is designed to turn crack stresses horizontally and dissipate the stress. GlasGrid® helps retard cracking from reflecting through a new asphalt overlay to the surface.



GlasGrid is a high strength, open fibreglass grid custom knitted in a stable construction and coated with an elastomeric polymer and self-adhesive glue. GlasGrid is supplied in strengths from 50kN/m up to 200kN/m.


GlasGrid is installed between 2 layers of asphalt. The existing asphalt surface should be clean and dry and all structurally distressed areas repaired. After rolling out GlasGrid onto the prepared surface, apply tack coat and the paving operation can commence once the tack coat has fully cured. A minimum overlay thickness of 40mm is required when using GlasGrid. This solution is well suited for council roads, highway applications, airports and industrial facilities.

Applications for GlasGrid include:

  • Asphalt reinforcement.
  • Resurfacing existing roads.
  • Over road widening joints.
  • New roads.



Supplied in the following grade

 ITEM GlasGrid 50/50
Roll weight 60kg
Roll size 2m x 100m


GlasGrid pavement reinforcement geogrids are manufactured to ISO 9001 quality standards. It is silica based and has a high melting point (+215 degrees C) and pressure-sensitive adhesive. GlasGrid is available in 2m wide rolls. It has excellent UV and oxidation resistance and performance is not affected by creep. It is easily milled and recycled and environmentally friendly.

 Features in short:

  • High stiffness, high modulus of elasticity, low elongation
  • No long-term creep
  • High melting point >232 deg. C
  • Open aperture design promotes aggregate interlock
  • Dramatically extends the life of roads, runways and parking lots
  • Lowers maintenance costs


GlasGrid pavement reinforcement geogrids are suitable for use in paving fabric applications. It has a low elongation and it bonds well on the levelling course. GlassGrid can be easily installed from the back of a ute and no special equipment is required.
