Fiberglass geogrid offers long-term structural stability, making it suitable for permanent projects. It is extensively used in asphalt pavement, soil stabilization, and embankment reinforcement, effectively preventing ground cracking and subsidence. By applying this product, the overlay thickness of asphalt can be reduced, significantly lowering construction costs and project investment.

How to Install Fiberglass Geogrid for Asphalt

1. Preparation

Surface Cleaning: Ensure the surface is clean, dry, and free from debris, dust, or loose materials. Use a broom, blower, or power washer if necessary.

Repair Existing Damage: Fill cracks, potholes, or uneven areas with suitable patching material and allow it to cure completely.

Tack Coat Application: Apply a tack coat (emulsified asphalt) to the prepared surface. This helps the geogrid bond securely to the asphalt layer.

2. Unrolling the Fiberglass Geogrid

Positioning: Unroll the fiberglass geogrid over the prepared surface, ensuring it lies flat and aligns with the direction of traffic or pavement stress.

Overlap Edges: Overlap adjacent rolls by 6-12 inches (15-30 cm) to ensure continuity and prevent gaps.

Cutting to Size: Use a utility knife or scissors to cut the geogrid to fit around curves, edges, or obstacles.

3. Securing the Geogrid

Temporary Fixing: Use nails, staples, or adhesive to temporarily secure the geogrid in place, especially on slopes or uneven surfaces.

Avoid Wrinkles: Smooth out any wrinkles or folds to ensure proper contact with the surface.

4. Applying the Asphalt Layer

First Layer of Asphalt: Pour and spread a thin layer of hot mix asphalt (HMA) over the geogrid. The thickness of this layer should be 1-2 inches (2.5-5 cm).

Compaction: Use a roller to compact the asphalt layer, ensuring the geogrid is fully embedded and bonded to the asphalt.
Second Layer of Asphalt: Apply the final layer of asphalt to achieve the desired pavement thickness. Compact again to ensure a smooth, durable surface.

5. Post-Installation Checks

Inspect for Gaps: Ensure there are no gaps or exposed areas of the geogrid.

Check Bonding: Verify that the geogrid is fully bonded to the asphalt layers.

Curing Time: Allow the asphalt to cool and cure completely before opening the pavement to traffic.

Tips for Successful Installation

Temperature Control: Ensure the asphalt is applied at the recommended temperature (typically 280-330°F or 140-165°C) for optimal bonding.

Avoid Traffic During Installation: Prevent vehicles or heavy equipment from driving over the geogrid before the asphalt layers are fully compacted.

Use Proper Equipment: Use a paver and roller suitable for the project size to ensure even distribution and compaction.

Benefits of Proper Installation

Reduces Reflective Cracking: Properly installed fiberglass geogrid minimizes cracks in the asphalt layer.

Enhances Durability: Improves the structural integrity and lifespan of the pavement.

Cost-Effective: Reduces long-term maintenance and repair costs.
