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.
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.
- Asphalt reinforcement.
- Resurfacing existing roads.
- Over road widening joints.
- New roads.
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 rolls from 1.5 m to 3.0 m wide. It has excellent UV and oxidation resistance and performance is not affected by creep. It is easily milled and recycled and environmentally friendly. 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. GlasGrid can be easily installed from the back of a ute and no special equipment is required.
Using GlasGrid can dramatically extend the life of roads, runways and parking lots and lower maintenance costs.
GlasGrid is installed between two 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 40 mm is required when using GlasGrid. This solution is well suited for council roads, highway applications, airports and industrial facilities.
