For more than 30 years, Tensar International Corporation has been a leading developer and manufacturer of geogrid products for improving trafficked surfaces. In fact,Tensar    Biaxial (BX) Geogrid was the world's first commercially available geosynthetic reinforcement grid for civil engineering applications.This innovative technology has allowed owners, engineers and contractors to realize the primary  features associated with geogrid in both paved and unpaved applications. which includes:

• Optimizing the thickness of pavement components
• Extension of pavement service life
• Stabilization of soft ground conditions

Tensar® TriAx® Geogrid

Thanks to a development team with a combined experience levelof over 150 years in manufacturing Tensar Geogrids, we have successfully re-engineered the geogrid structure  by creating a revolutionary new product  specifically designed  for trafficked surfaces - Tensar' TriAx Geogrid.

With its unique triangular structure, TriAx Geogrid represents a revolutionary advancement  in geogrid technology. Its multi-directional properties leverage the triangular geometry,one of construction's most stable shapes. to provide a new level of in-plane stiffness.The transition  from a rectangular to a triangular grid aperture, coupled with an increase in rib thickness and junction efficiency, offers the construction industry a better alternative  to conventional materials and practices.

Through ongoing investment, product  development and innovation, Tensar International is continuing to deliver the industry's most cost-effective solutions  for achieving optimal performance for both permanent  paved surfaces and temporary solutions over soft soil.

Applications

TriAxGeogrid from Tensar International Corporation offers unrivaled performance in paved and unpaved applications. Combined with the technical support and expertise of the Tensar team,TriAx Geogrid is the future of geogrid technology and, with its unmatched performance, the industry's best solution for building lower cost, longer lasting and more reliable trafficked surfaces.

Paved Applications

Paved systems often fail prematurely because of progressive lateral displacement and weakening of the granular base course. TriAx Geogrid improves the overall stiffness of roadways, parking lots,taxiways,runways, aprons. intermodal facilities and other structures that support vehicular traffic, leading to enhanced performance.Improved performance of trafficked sections optimizes overall life-cycle costs by minimizing maintenance and rehabilitation intervals common to both ftexible and rigid pavements.

Unpaved Applications

Weak subgrades are a common problem  during the construction of haul roads, parking lots,working surfaces, staging areas, storage yards and other unpaved structures.TriAx Geogrid provides a simple solution for stiffening the granular platform and reducing subgrade stress.Enhanced constructability greatly improves site access while significantly reducing up-front costs and future maintenance.

The Spectra System from Tensar Earth Technologies improves flexible pavement systems in three ways:

• Simplifies construction
• Extends service life
• Reduces required materials

Not only does this system allow access and construction in less than ideal situations, it also offers a predictable engineered solution. This solution relies on Tensar ® Biaxial (BX) Geogrids and crushed aggregate base acting together to create a stronger composite structure, which increases the performance of the underlying subgrade or the aggregate base course.

The result is a more durable and cost-efficient pavement. The Spectra System and the tested design principles it relies upon achieve these results by two distinct but related methods:

• Subgrade Improvement
• Base Course Reinforcement

The Spectra System has been used successfully for:

• Paved highways and secondary roads
• Parking areas for commercial and industrial facilities
• Airport runways and taxiways
• Truck freight distribution centers and terminals
• Heavily loaded equipment yards at port, rail, intermodal, and industrial facilities
• Haul roads

Weak subgrades are a common problem in pavement construction. As the foundation for pavement, subgrade failure will lead to rapid deterioration of the pavement structure.

Traditionally, weak or pumping subgrades have been removed and replaced with imported fill or stabilized chemically. Both options are expensive and time- consuming, especially when compared to the Spectra solution.

The Spectra System improves the performance of the existing subgrades by distributing loads over a wider area which reduces pumping and shear failure while maximizing the load bearing capacity of the subgrade.

When undercutting or backfilling is required, Tensar BX Geogrids can reduce or even eliminate the need for undercutting, removing weak or contaminated soils, and importing expensive, select fill. The results are faster construction and lower costs.

When lime or cement stabilization  is considered, BX Geogrids can present an alternative. Support can be obtained without the time, cost, or environmental hazards of chemical stabilization methods, and without impeding internal drainage.

When deep fill sections are required, BX Geogrids can reduce the thickness of the fill layer by as much as 50% while achieving the needed load distribution. The result is reduced select fill costs and faster job completion.

When building paved or unpaved roads, parking lots, airports, taxiways, rail lines, or even foundations, subgrade improvement with Tensar BX Geogrids make the job more economical, save on materials, and reduce construction time. Over any weak soil, BX Geogrids distribute imposed load(s), improve bearing capacity, reduce rutting, and provide an alternative to costly conventional methods.
