Road Construction Nonwoven Geotextile Durable Reinforcement with Superior

Product Specification

Product Overview

Our Needle-Punched Nonwoven Long-Fiber Geotextile is a premium geosynthetic fabric engineered for applications demanding exceptional tensile strength, long-term stability, and resistance to mechanical stress. Made from continuous polyester (PET) or polypropylene (PP) filaments bonded through advanced needle-punching technology, this geotextile outperforms traditional short-fiber variants in heavy-duty scenarios such as road construction, embankment reinforcement, and landfill engineering. Its interlocked filament structure ensures uniform load distribution, superior puncture resistance, and extended service life—making it the ultimate choice for infrastructure projects requiring reliability and durability.

Key Advantages

1. High Tensile Strength

   • Filament Structure: Continuous fibers provide multidirectional strength (15–40 kN/m), ideal for load-bearing applications.

   • Elongation Control: Low elongation under stress (<50%) maintains structural integrity during ground movement.

2. Enhanced Durability

   • Puncture & Tear Resistance: Withstands sharp aggregates, roots, and construction stresses.

   • UV & Chemical Stability: Resists degradation from sunlight, acids, alkalis, and biological agents (pH 2–13).

3. Balanced Permeability

   • Optimal Flow Rate: Hydraulic conductivity of 0.1–1.5 cm/s (ASTM D4491) ensures efficient drainage without soil loss.

   • Clogging Resistance: Open yet stable structure retains fine particles while allowing water passage.

4. Cost-Effective Longevity

   • 50+ Year Lifespan: Minimal maintenance required compared to short-fiber geotextiles in high-stress environments.

Long-Fiber vs. Short-Fiber Geotextiles: Critical Differences

Applications

• Road & Railway Construction: Separation and stabilization of subgrade and aggregate layers.

• Landfill Liners & Caps: Reinforcement over geomembranes and leachate collection systems.

• Steep Slope Stabilization: Prevents soil erosion on embankments and retaining walls.

• Coastal Protection: Resists wave action and scour in breakwaters and revetments.

• Industrial Pads: Stabilizes ground under heavy machinery or storage areas.

Technical Specifications

• Material: 100% Virgin Polyester (PET) or Polypropylene (PP).

• Weight: 150–1500 g/m² (customizable).

• Thickness: 1.0–8.0 mm (ASTM D5199).

• Tensile Strength: 15–40 kN/m (ASTM D4632).

• CBR Puncture Resistance: 2000–6000 N (ASTM D6241).

• UV Resistance: ≥80% strength retention after 1000 hours (ASTM D4355).

• Roll Sizes: 2–8m width × 50–200m length.

Why Choose Long-Fiber Geotextiles?

✅ Heavy-Duty Performance: Engineered for high-stress, high-traffic environments.
✅ Consistent Quality: Uniform filament structure ensures no weak points.
✅ Sustainability: Recyclable and reduces aggregate use in construction.
✅ Custom Solutions: Tailored weight, width, and additives (e.g., fire retardant).

Installation Guidelines

1. Subgrade Preparation: Compact soil and remove sharp debris.

2. Roll Deployment: Overlap edges by 300–500mm; secure with staples or anchors.

3. Aggregate Placement: Cover immediately to prevent UV exposure and displacement.
