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.

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:
- 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.
