Tensar International has launched an enhanced version of its market-leading TriAx® Geogrid product which significantly improves the performance of any roadway’s aggregate base course (the layer of stone installed between the surface pavement layer and the subgrade or foundation soils). The new TX8 has been proven to better confine and stabilize the base, reducing rutting and fatigue, while providing much longer lasting pavement compared to conventional materials and practices.

“Contractors are hard pressed to balance prompt project delivery with cost and quality. At the same time, roadway owners want more sustainable performance for their infrastructure,” said Scott Edgecombe, EVP & GM Western Hemisphere for Tensar International. “TX8 helps construction companies and road/highway contractors save time and money by using less aggregate and asphalt to achieve better road uniformity, stability, and sustainability,” Edgecombe said.

For more than 30 years, Tensar has been a valued partner to the road construction industry, providing innovative solutions for agencies and engineers focused on reducing costs and improving pavement performance. Tensar TriAx Geogrid is a stiff polymer mesh specifically designed to substantially stabilize and improve the performance of trafficked surfaces, providing multi-directional properties, while offering the construction industry an improved alternative to conventional materials and practices. It 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 process yields a more efficient product that delivers optimal in-service stress transfer from the aggregate to the stabilizing geogrid.

TX8 expands on the strong performance reputation of TriAx Geogrid, providing five key benefits:

  1. Significantly reduce construction and maintenance costs
  2. Improve Pavement Life
  3. Shorten Project Timelines
  4. Reduce Utility Impacts
  5. Reduce Carbon Emissions

Prior to launching the product, Tensar completed full-scale testing to evaluate the performance of TX8 stabilized highway pavements over stiff subgrade conditions. The latest testing is the Accelerated Pavement Testing (APT) at the US Army Corps of Engineers Engineering Research and Development Center (ERDC). The Corps tested the new TX8 product, applying more than 800,000 ESALs, in heavily controlled and instrumented conditions.

Ease of Use

For design engineers, Tensar has made it easy to incorporate TriAx Geogrid, including TX8, into the design process by creating SpectraPave4-PRO (SP4-PRO) software. SP4-PRO is based on significant testing, and has been 3rd party peer reviewed. This powerful tool allows engineers to evaluate design options and optimize pavement performance by incorporating TriAx Geogrid. In addition to the design tools and software, Tensar offers complimentary pavement evaluation and site assessments to determine the best TriAx Geogrid for each project.

For contractors, the ease of use of Tensar TriAx Geogrid starts with the first installation. More and more contractors are discovering how easy it is to utilize the product on their jobsite, with no specialized labor needed for installation.



For more than 30 years, Tensar’s innovative ground stabilization solutions have proven ideal for many kinds of construction and subgrade improvement projects, including paved and unpaved roads, car parks, airfields, heavy duty pavements and working platforms.

We also offer full technical support including design software, expert advice and site assessments.
