Tensar Triax TX140

The Spectra® Roadway Improvement System is a comprehensive approach for optimizing pavement performance using Tensar® TriAx® Geogrids. The system uses the multiple benefits of a mechanically stabilized layer (MSL), which consists of aggregate stabilized by TriAx Geogrid, to form a stiffer and more robust structure. But the Spectra System is more than just the MSL. It includes all the expertise, experience, design tools, support and service that Tensar International delivers – a complete solution for pavement design engineers and contractors.

Tensar® TriAx® (TX) Geogrids

Tensar® TriAx® Geogrid is an advanced product specifically designed for trafficked surfaces. TriAx Geogrid’s multi-directional properties leverage triangular geometry, one of construction’s most stable and widely utilized shapes, to provide an enhanced level of in-plane stiffness. Its triangular structure, coupled with improved rib and junction geometry, offers the construction industry an improved alternative to conventional materials and practices.

TriAx Geogrid is manufactured from a punched polypropylene sheet oriented in multiple, equilateral directions to form its triangular apertures, resulting in high radial stiffness throughout the full 360 degrees. This feature yields a more efficient product that delivers optimal in-service stress transfer from the aggregate to the stabilizing geogrid.
