Earthwork Products Fiberglass Geogrid For Retaining Wall Reinforcement

Fiberglass geogrid is a high-performance geosynthetic material made of glass fiber through weaving, coating and other processes. It has excellent mechanical properties and weather resistance.

Key characteristics

1. High strength and low elongation

• The tensile strength can reach 65-100KN, and the elongation at break is less than 3%, which can effectively disperse the load stress and enhance the bearing capacity of the soil.
• The inorganic characteristics of glass fiber give it stable physical and chemical properties, corrosion resistance, aging resistance, and long service life.

2. Thermal stability and creep resistance

• The melting point of glass fiber exceeds 1000℃, and its performance is stable at high temperature, which is suitable for asphalt paving and other scenes.
• No long-term creep, and the structure can still maintain stability under long-term load.

3. Compatibility with asphalt

• The surface is coated with modified asphalt, which is tightly combined with the asphalt mixture to prevent interlayer separation and enhance the integrity of the road surface.

Asphalt Fiberglass Geogrid :

Main application scenarios

1. Road engineering

• Asphalt pavement reinforcement: delay reflective cracks, reduce rutting and fatigue cracks, and extend service life.
• Old road reconstruction: add to cement concrete or old asphalt pavement to inhibit crack expansion.
• Roadbed reinforcement: improve the bearing capacity of soft soil foundation, control settlement, and evenly distribute stress.

2. Protection and slope engineering

• Used for retaining walls, slope protection, riverbank/coastal protection, to prevent landslides and soil erosion.

3 Special scenarios

• Airport runway/parking lot: enhance the ground's compressive strength and reduce deformation caused by vehicle loads.
• Environmental protection engineering: slope protection and drainage system reinforcement of landfills and sewage treatment plants.

Construction methods and technical advantages

1. Construction methods

• Anchoring method: Fix the grille by fixing iron sheets and nails, suitable for the junction of new and old pavements.
• Self-adhesive method: Directly stick to the base layer, simplify the construction process, and do not require special equipment.

2. Technical advantages

• Delaying reflective cracks: Dispersing stress through the hard interlayer effect and reducing crack expansion.
• Anti-rutting and low-temperature cracking: Limit aggregate displacement and improve the deformation resistance of asphalt mixture.

Selection and precautions

Specification selection: The mesh size should be 0.5-1 times the maximum particle size of the asphalt surface layer to ensure effective interlocking.

Construction environment: The base layer needs to be cleaned to avoid sharp objects damaging the grille; the filler should be covered in time after laying to prevent ultraviolet aging.
