Product Features
- High tensile strength and low elongation
- No long-term creep and good thermal stability
- Good physic and chemical stability, strong resistance to biologic erosion and climate changes
- Good affinity with asphalt and cement concrete.
Applications
Civil engineering
Reinforcement of roadbeds:
Function: Disperse the load and reduce the uneven settlement;
Case: Substitute steel-plastic grating in soft foundation treatment of high-speed railroad, reducing maintenance cost by 30%.
Slope protection:
Program: grating + vegetated concrete (2-3 times higher slip resistance).
Traffic engineering
Asphalt pavement enhancement:
Laying between asphalt layers, delaying reflection cracks (fatigue life extended by 50%);
Construction temperature: 160-180℃ (basalt fiber has significant advantages in high temperature resistance).
Water conservancy engineering
Seepage control structure of embankment dam:
Composite use with geomembrane to resist hydraulic scour;
Requirement of tensile strength: ≥100 kN/m (bi-directional grating).
Mining ecological restoration
Tailings dam reinforcement:
Acid corrosion resistance (pH 3-4 environment), service life > 50 years.
