Lianyi Asphalt reinforcement fiberglass geogrids are designed specifically as an interlayer for asphalt reinforcement. Our fiberglass geogrid systems work to enhance pavement life and performance while helping to reduce maintenance costs
Fiberglass geogrid is a composite product meaning that the geogrid is bonded to a non-woven geotextile. It provides moisture proofing and water resistance benefits while creating a strong bond of the asphalt layers over the tack coat surface. This bond ensures that the reinforcing geogrid is in a position to effectively accept and distribute tensile stresses.
Fiber Glass Geogrid is a geogrid made from fibre glass filaments, encased by a polymeric protective coating. This results in a high modulus of elasticity at low elongation that can offer a large increase in the effective service life of a road pavement reinforcement structure and bitumen layer crack control
Fiber Glass Geogrid is composed of a reticular structural material made of glass fiber with bitumen coating. Fiber Glass Geogrid is warp knitted with oriental structure which gives full play of yarns strength and improves its mechanical property to make the product high tensile, tearing and Fiber Glass Geogrid creep-resistant. Fiber Glass Geogrid creases the cost of construction, also prolongs the service life of the pavement.
Benefits:
- Suitable for all types of asphalt mixes.
- Minimizes both thermal and stress related reflective cracking.
- Reduces pavement rutting under high ambient temperatures and intense wheel loads.
- Increases the fatigue life of pavements with weak foundations.
- Extends pavement life.
- Provides cost benefits by increasing pavement life cycle.
- Fast, easy installation and recyclable.
- Reduces overlay thickness to a minimum of 50 mm.
Applications:
- Airport runways, taxiways, roads, bridges, parking lots, jointed concrete highways to control reflective cracking.
- High traffic pavement to control of rutting.
- New highway construction, and other road maintenance/repair jobs to improve pavement life.
