High Tensile 100kn Basalt Geogrid For Road And Bridge Pavement Fiberglass Geogrid
Basalt Geogrid mesh is a kind of reinforcement product which uses the anti-acid and alkali basalt continuous filament (BCF) to produce gridding base material with advanced knitting process, sized with saline and coated with Bitumen or Polymer.
Basalt geogrid is designed for reinforcing road and highway overlays to prolong the pavement lifespan by reducing the effects of reflective cracking caused by traffic loading, age hardening and temperature cycling.
Pavement life between maintenance can be prolonged significantly. Basalt reinforcing mesh makes it possible to reduce thickness of asphalt concrete pavement up to 20%.
Basalt grid performance advantages
Excellent mechanical properties
1. High strength and low elongation
The tensile strength of basalt fiber is as high as 90-200kN/m (in both warp and weft directions), and the elongation at break is ≤4%, which is significantly higher than that of glass fiber or polyester fiber. Its high modulus characteristics can effectively disperse stress and reduce road settlement and deformation.
2. No long-term creep
Under long-term load, basalt fiber will not creep, ensuring long-term stability of material performance, suitable for heavy-loaded roads and airport runways.
Extreme environment resistance
1. High and low temperature resistance
- High temperature resistance: melting point >1500℃, long-term use temperature -260℃~650℃, can withstand high temperature of asphalt paving (above 190℃).
- Low temperature resistance: mechanical properties are still maintained in severe cold areas (such as below -40℃), and the ability to resist freeze-thaw cycles is strong.
2. Corrosion resistance and anti-aging
Acid, alkali, salt corrosion and ultraviolet resistance, strong chemical stability, service life can reach 50-100 years, suitable for harsh environments such as coastal areas and high cold.
Synergy with asphalt materials
1. Excellent compatibility
The surface is coated with modified asphalt or PVC, which is closely combined with the asphalt mixture to avoid stratification and improve the integrity of the road surface.
2. Interlocking and limiting effect
The mesh structure limits the movement of aggregates, forming a composite mechanical interlocking system, and enhancing the asphalt layer's ability to resist rutting and displacement.
Anti-fatigue and anti-cracking performance
1. Disperse stress
Disperse the wheel load stress, reduce stress concentration, and delay the generation of reflective cracks and rutting.
2. Anti-low temperature shrinkage cracking
Increase the transverse tensile strength of the asphalt surface layer, resist the tensile stress caused by low temperature shrinkage, and reduce shrinkage cracking.
Economy and applicability
1. Cost-effectiveness
Although the unit price is higher than polyester fiber, it has a long life and low maintenance cost, and is suitable for heavy-duty and high-demand projects.
2. Applicable in multiple scenarios
- Road engineering: asphalt pavement reinforcement, old road renovation.
- Civil engineering: roadbed reinforcement, slope protection and flood control.
- Special scenarios: high-cold areas, high-temperature areas (such as airport runways).
