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 aperture, 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. read more »
The Spectra System can actually increase the effective strength of the pavement structure while at the same time enhancing its internal drainage characteristics. Tensar Biaxial (BX) Geogrid and aggregate fill interact to create a stiffer composite structure. The result is a stronger, yet not brittle, pavement that's more economical, better performing, more durable and predictable - as proven with more than 375 million square meters of installations to date - or the equivalent of over 50,000 lane miles. That's enough to support a two lane highway around the circumference of the earth!
Dr. J. P. Giroud and Dr. Jie Han recently released new technology for subgrade improvement design. Their work is the most comprehensive advancement in the structural design of unpaved roads in the last 20 years. Tensar International Corporation has taken this technology a step further by developing SpectraPave3™ Software based on Mechanistic-Empirical (M-E) design research conducted by the University of Illinois Urbana-Champaign.
