Fiberglass Nonwoven Asphalt Overlay | Premium Pavement Reinforcement Solution
Product Overview
Our Fiberglass Nonwoven Asphalt Overlay is a high-performance, composite material designed to extend pavement lifespan by reinforcing asphalt surfaces. Combining a durable nonwoven fiberglass mat with a polymer-modified asphalt coating, it delivers superior resistance to cracks, moisture, and heavy traffic. Ideal for highways, municipal roads, and commercial parking lots in the U.S. and Canada.
Key Features & Benefits
1. Exceptional Durability
- Glass fiber reinforcement resists tensile stress, preventing reflective cracks.
- Modified asphalt coating ensures long-term adhesion and flexibility (-30°C to 80°C).
2. All-Climate Performance
- Withstands freeze-thaw cycles (critical for Canada) and UV exposure (southern U.S. regions).
3. Easy Installation
- Prefabricated rolls for fast deployment; compatible with standard asphalt paving equipment.
4. Cost-Effective Maintenance
- Reduces repair frequency by up to 50% compared to traditional overlays.
5. Eco-Friendly
- Contains recycled materials; LEED® contribution potential.

Applications
- Function:
- Seals and reinforces aged asphalt/concrete pavements by bridging existing cracks (up to 5mm wide) and preventing reflective cracking.
- Acts as an interlayer between old and new asphalt layers, extending pavement life by 8–12 years.
- Use Cases:Technical Note: Compatible with infrared thermal repair for seamless integration.
- Urban road resurfacing (e.g., pothole-prone intersections).
- Repairing alligator cracks on highways without full-depth reconstruction.
-
- Function:
- Embedded within asphalt layers to distribute load stress, reducing rutting and fatigue cracking under heavy traffic (e.g., 80+ kN axle loads).
- Enhances tensile strength by 40% compared to non-reinforced asphalt (per ASTM D7460 testing).
- Use Cases:
- Highways: Critical for jointless continuous paving in expansion zones.
- Airport Runways: Withstands jet blast and fuel exposure (FAA-approved grades available).
- Technical Note: Requires hot-mix asphalt (HMA) compaction at 150–160°C for optimal bonding.
- Function:
Function:
Forms a non-permeable barrier against water ingress, preventing corrosion of steel reinforcements in concrete bridge decks.
Resists chloride ion penetration (ASTM C1543 compliance), crucial for coastal regions.
Use Cases:
Bridge Decks: Installed under asphalt wearing courses (e.g., orthotropic steel bridges).
Underground Parking: Blocks rising dampness and oil spills.
Technical Note: Pair with torch-applied modified bitumen for vertical surfaces.
- Function:
- Lighter-grade variants (1.5–2.5mm thickness) provide crack resistance for low-speed, low-load areas.
- UV-stabilized surface resists fading and degradation in driveways.
- Use Cases:Technical Note: DIY-friendly with cold-adhesive backing options.
- Home Driveways: Eliminates seasonal cracking in freeze-thaw climates.
- Community Lanes: Ideal for HOA-maintained roads with 10–50 vehicles/day.
