Basalt Fiber Geogrid Highway Railway Foundation Reinforcement
Basalt Fiber Geogrid is a semi-rigid geosynthetic material engineered from high-strength basalt fibers, woven into a grid structure and coated with asphalt or polymer for enhanced durability. Key features:
Superior Strength: High tensile strength in both warp/weft directions (up to 300 kN/m) with low elongation (<3%)
.Extreme Durability: Resists temperatures from -260°C to 800°C, UV exposure, and chemical corrosion
.Eco-Friendly: Made from natural basalt, no carcinogenic risks, and recyclable
.Applications: Pavement reinforcement, slope stabilization, railway subgrade, and mine tunnel reinforcement
.Raw Material Preparation: Basalt rock is melted at 1,450–1,500°C and drawn into continuous fibers
.Weaving: Fibers are warp-knitted into grid patterns using advanced biaxial looms
.Coating: Surface treated with asphalt, polymer, or silane for adhesion and weather resistance
.Quality Control: Tensile strength, thermal stability, and corrosion tests ensure compliance with ISO 9001
.Avoid Mechanical Damage: Protect from sharp tools or excessive bending during installation.
Chemical Resistance: While resistant to most acids/alkalis, avoid prolonged contact with strong oxidizers
.Temperature Sensitivity: Ensure installation in dry conditions; avoid freezing/thawing cycles.
Inspection: Monitor for wear (≤30% strength loss) and replace damaged sections promptly.
