fiberglass geogrid

 1.High Tensile Strength

• Made from continuous filament fiberglass, offering extremely high tensile strength at low elongation (typically ≤3-4%).

• Effectively absorbs and distributes stress loads in asphalt pavements and soil structures.

2. Excellent Thermal Stability

• Maintains dimensional stability under high temperatures (up to 280°C / 536°F), making it ideal for hot-mix asphalt (HMA) overlay applications.

• Resists thermal deformation during paving and compaction.

3. Alkali Resistance (with coating)

• Standard fiberglass is susceptible to alkali attack, but quality geogrids feature a specialized coating (e.g., acrylic, epoxy, or bituminous/SBR latex) that provides excellent alkali resistance.

• Ensures long-term durability in high-pH environments like cement-stabilized bases.

4. Low Creep & Low Elongation

• Unlike polyester geogrids, fiberglass exhibits minimal creep (permanent deformation under long-term load).

• Maintains reinforcement effectiveness over decades with very little stretch.

1. Road & Pavement Engineering

• Asphalt Pavement Reinforcement

• Reflective cracking prevention – Installed between old concrete/asphalt pavement and new asphalt overlay.

• Fatigue crack reduction – Extends service life of highways, runways, and urban roads.

• Rutting resistance – Reduces permanent deformation under heavy traffic loads.

• Pavement Maintenance & Repair

• Pothole repair reinforcement – Provides structural integrity to patched areas.

• Thin asphalt overlays – Enables thinner pavement sections (cost & material savings).

2. Airport Runways & Taxiways

• Runway overlay reinforcement – Withstands high dynamic loads from aircraft takeoff/landing.

• Apron & taxiway strengthening – Prevents differential settlement and surface cracking.

• Reflective crack control – Critical for extending runway service intervals.

3. Railway Engineering

• Ballast reinforcement – Stabilizes railway ballast layers, reducing lateral movement.

• Subgrade stabilization – Improves load distribution beneath tracks.

• Reduced maintenance cycles – Minimizes track settlement and ballast degradation.

4. Retaining Walls & Abutments

• MSE walls (Mechanically Stabilized Earth) – Acts as horizontal reinforcement layers in soil.

• Bridge abutment backfill – Prevents lateral soil pressure and settlement.

• Steep slope reinforcement – Enables steeper slope angles with improved stability.

5. Slope & Embankment Stabilization

• Slope surface reinforcement – Prevents shallow slides and erosion.

• Embankment over soft soil – Distributes loads and limits settlement.

• Landslide repair – Provides tensile strength to unstable soil masses.

Q1: What are the standard tensile strength grades?

A: Common grades (kN/m, both directions):

30 kN/m – Light duty (pedestrian, light pavement)

50 kN/m – General road reinforcement

100 kN/m – Highways, runways

150 kN/m – Heavy-duty roads, ports

200+ kN/m – Mining, industrial heavy loads

Q2: What are the standard roll sizes?

A:

Width: 1m, 2m, 4m, 6m (custom up to 8m)

Length: 50m, 100m, 150m (custom 10m–500m)

Aperture (grid opening): 12.7×12.7 mm, 25.4×25.4 mm, 40×40 mm

Q3: What is the temperature resistance of fiberglass geogrid?

A: Fiberglass geogrid maintains stability from -100°C to +280°C (-148°F to 536°F), making it ideal for hot-mix asphalt (HMA) applications where pavement temperatures can reach 160-180°C during laying.

Q4: Is fiberglass geogrid alkali-resistant?

A: Raw fiberglass is vulnerable to alkali attack. However, high-quality fiberglass geogrids are coated with acrylic, epoxy, or SBR latex which provides excellent alkali resistance, suitable for cement-stabilized bases and high-pH environments.

Q5: Does fiberglass geogrid creep over time?

A: No. Fiberglass geogrid has extremely low creep (permanent deformation under long-term load) compared to polyester. It maintains reinforcement effectiveness for decades with minimal stretch (typically <0.1% over 10 years under sustained load).

Q6: What is the elongation at break?

A: Typically ≤3-4% for standard fiberglass geogrid. This low elongation means the geogrid stiffens quickly under load, providing immediate stress transfer and crack prevention.
