Multi-directional trafficking performance

The near isotropic stiffness properties of TriAx geogrid suggests that the product will perform consistently well, regardless of the wheel path direction. This has been confirmed by multi-directional trafficking tests in the Nottingham Transportation Engineering Centre (NTEC).

Deformation measurements showed that TriAx geogrid performed equally well in all directions. This is in contrast with conventional biaxial geogrids, which, although very beneficial, showed a reduced effectiveness when trafficked at an orientation of 45 degrees to the rib direction, against comparable trafficking parallel to the rib direction.

The polar diagram compares the tensile stiffness of Tensar biaxial and TriAx geogrids through 360°, with TriAx exhibiting near isotropic properties.
