Fiberglass Reinforcement Geogrid Coated With Elastomeric Polymer For Basal Construction

Fiberglass geogrid is knitted by glass fiber filaments and coated with bitumen to provide a good bond with the asphalt layers, can strengthen the asphalt layer, extend the service life ot pavement layers and decrease the occurrence rate of reflective cracking under cyclic traffic load.

Maintenance requirements and precautions

1. Maintenance during the construction phase

• Base treatment: Before laying, the base needs to be thoroughly cleaned to ensure that there are no sharp objects, oil stains and loose particles to prevent damage to the grille or bonding failure.
• Laying specifications:
• When using the self-adhesive method, it is necessary to ensure that the adhesive surface fits tightly, and the overlap width is 75-150mm vertically and 25-50mm horizontally to avoid wrinkles or twists.
• When using the anchoring method, it is necessary to avoid nailing the nails directly into the glass fiber layer to prevent fiber breakage.
• Timely covering: After laying, the asphalt mixture or filler should be covered as soon as possible to reduce the aging of the adhesive layer caused by direct exposure to ultraviolet rays.

2. Maintenance during the use phase

• Regular inspection: Focus on monitoring whether there is debonding or local damage in the joints and edge areas, and repair them in time to prevent cracks from expanding.
• Chemical pollution protection: If used in chemical areas, it is necessary to regularly remove surface oil or corrosive substances to avoid long-term infiltration affecting the performance of the coating.

Key measures to extend durability

1. Model selection optimization

• Select the corresponding tensile strength (such as 20-120KN/m) and mesh size (preferably 0.5-1 times the maximum particle size of asphalt aggregate) according to project requirements to ensure the interlocking effect.

2. Environmental adaptation design

• Anti-UV coating models are selected in high-ultraviolet areas; drainage design is strengthened in rainy and humid areas to reduce water damage.

3. Composite technology application

• Combine geotextile or steel-plastic grid to form a composite structure to improve impact resistance and fatigue resistance, suitable for heavy-load traffic sections.
