How Fiberglass Geogrid with Geotextile Prevents Reflective Cracking in Asphalt?
Fiberglass Geogrid with Geotextile is a highly effective solution for preventing reflective cracking in asphalt pavements. Reflective cracking occurs when cracks from an underlying layer (such as a base or subbase) propagate through the asphalt surface layer, often due to thermal expansion, traffic loads, or settlement.
1. Reinforcement of the Asphalt Layer
High Tensile Strength: Fiberglass geogrid provides exceptional tensile strength, which helps distribute loads more evenly across the pavement. This reduces stress concentrations that can lead to cracking.
Load Distribution: By reinforcing the asphalt layer, the geogrid minimizes the impact of traffic loads, preventing cracks from forming or propagating.
2. Interlayer Barrier Function
Geotextile Backing: The geotextile layer acts as a barrier between the old and new asphalt layers. It prevents cracks in the underlying layer from reflecting through to the surface.
Stress Absorption: The geotextile absorbs and dissipates stress caused by thermal expansion, contraction, and traffic loads, further reducing the risk of cracking.
3. Improved Bonding Between Layers
Enhanced Adhesion: The combination of fiberglass geogrid and geotextile ensures a strong bond between the asphalt layers. This prevents delamination and improves the overall structural integrity of the pavement.
Flexibility: The geogrid's flexibility allows it to move with the pavement, accommodating minor movements without cracking.
4. Crack Bridging
Crack Arrest Mechanism: When cracks begin to form in the underlying layer, the fiberglass geogrid bridges the cracks, preventing them from propagating to the surface.
Durability: Fiberglass is resistant to fatigue, ensuring long-term performance even under heavy traffic conditions.
