Geocomposite Triax TX BX Grid Mesh Reinforce Composite Geogrid For Road Subgrade Geotextile Separation

Geocomposite Triax Geogrid Decsription :

A Triax Geogrid Geocomposite combines a triaxial geogrid (typically made of polypropylene or polyester) with other geosynthetics (e.g., nonwoven geotextiles) to enhance multifunctional performance. Key components:

• Triax Geogrid Core: Hexagonal grid structure with equal strength in multiple directions (isotropic), providing 360° load distribution

• Geotextile Layer: Needle-punched nonwoven fabric (e.g., 150–300 g/m²) bonded to the grid for filtration/separation

2. Key Properties
Property Typical Value Test Standard
Tensile Strength 20–50 kN/m (radial) ASTM D6637
Aperture Size 30–50 mm (hexagonal) ISO 10318-1
Junction Strength ≥90% of rib strength ASTM D7737
Advantages over Biaxial Geogrids:

Isotropic Reinforcement: Equal strength in all directions, ideal for dynamic loads
Integrated Filtration: Geotextile prevents soil migration while allowing drainage

Applications :
A. Road & Rail Infrastructure
Base Reinforcement: Reduces aggregate thickness by 30–50% in flexible pavements

Subgrade Stabilization: Prevents rutting in soft soils (CBR < 3) by distributing loads radially

B. Retaining Structures
Mechanically Stabilized Earth (MSE) Walls: Triax grids reduce lateral earth pressure by 40% compared to biaxial grids

C. Landfill & Mining
Liner Protection: Geotextile layer shields geomembranes from puncture (CBR puncture ≥3 kN
