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
