Tensar Biaxial (BX) Geogrid wasthe world’s first commercially available geogrid for civilengineering applications. This innovative technologyhas allowed owners, engineers and contractors torealize the primary benefits associated with geogrid inboth paved and unpaved applications, such as: Optimizing the thickness of pavementcomponents Extension of pavement service life Stabilization of soft ground conditionsWith its unique triangular structure, TriAx Geogridrepresents a revolutionary advancement in geogridtechnology. Its multi-directional properties leveragetriangular geometry, one of construction’s most stableshapes, providing greater stability and stiffness. Thechange from a rectangular to a triangular grid aperture,coupled with an increase in rib thickness and junctionefficiency, offers the construction industry a betteralternative to conventional materials and practices.Through ongoing investment, product developmentand innovation, Tensar International continues todeliver the industry’s most cost-effective solutions forachieving optimal performance for both permanentpaved surfaces and temporary solutions over soft soil.Thanks to a development team with a combinedexperience level of more than 150 years inmanufacturing Tensar Geogrids, Tensar successfullyre-engineered the geogrid structure by creating arevolutionary new product specifically designed fortrafficked surfaces – Tensar TriAx Geogrid.The unique structure of Tensar TriAx Geogrid provides a highdegree of in-plane stiffness, improving performance.3
TriAx Geogrid offers an innovative ribstructure with near isotropic propertiesand advanced characteristics thatimprove upon the time-testedperformance of our industry-leadingbiaxial geogrid.TriAx GeogridTensar Biaxial GeogridCompared with a conventional biaxial geogrid, TriAx Geogrid hasa greater rib depth contributing to improved confinement.TriAx Geogrid Delivers Performance in Three Dimensions BETTER INTERLOCK AND CONFINEMENTBiaxial geogrids offer tensile stiffness primarily in twodirections. TriAx Geogrids have three principaldirections of stiffness that are further enhanced bytheir rigid triangular geometry. The triangular geometryprovides a significantly different structure than othercommercially available geogrids, delivering high radialstiffness throughout the full 360 degrees.Three-dimensional load distribution acts in a radialmanner at all levels within the aggregate. This helps toensure optimum performance of geogrid stabilizationin a mechanically stabilized layer. Thus, TriAx Geogrid isengineered to outperform Tensar BX Geogrids bybetter distributing radial stresses.TRIANGULAR APERTURE GEOMETRYAggregate particles interlock within the geogrid and areconfined within the apertures. These interactionscreate a stiffened composite layer with improvedperformance characteristics. The structural propertiesof the mechanically stabilized layer are influenced bythe magnitude and depth of the confined zones.4The unique shape of the geogrid ribs confines aggregate particles dueto its high stiffness and the strength at the corners (junctions), justlike a rack confines billiard balls.Empirical and mechanistic research performed withTriAx Geogrid aid in quantifying this stiffnessenhancement.TriAx Geogrid is formed with the same square-edged ribas our existing Tensar BX Geogrid but with an enhancedrib profile for confining aggregate material. Full-scaleresearch has proven that geogrids manufactured withdeeper ribs and square edges outperform geogrids withrounded edges and thinner ribs (1992, USACE ReportNo. DOT/FAA/RD-92-25).JUNCTION INTEGRITY AND EFFICIENCYTriAx Geogrids’ unique aperture geometry forms ahexagonal junction shape with superior junctionstrength and stiffness to mitigate radial stressimparted from a trafficked surface. This makes it theoptimal geogrid for the application.TriAx Geogrid is manufactured from an extruded sheetof polypropylene. During the manufacturing process,each sheet is punched with an array of holes and thencarefully stretched to create triangular apertures withgreater confinement characteristics. This process yieldsEfficient junctions help to transfer the load applied to amechanically stabilized layer to the geogrid. If the junctions arenot efficient, then the geogrid will not work as effectively.

This meets the needto effectively and uniformly distribute loads for bothpaved and unpaved applications.SUPERIOR PERFORMANCE FOR PAVEDAND UNPAVED ROADSTriAx Geogrid’s near isotropic stiffness characteristicscontribute to its improved performance in comparisonto Tensar BX Geogrids in trafficked applications. Suchcharacteristics are ideal for improving the service life ofpaved and unpaved surfaces while further reducingexcavation and pavement component thicknessrequirements.LESS STRESS ON SUBGRADESimparted by in-service loads. This new feature resultsin a better reduction of subgrade stresses whileenhancing the durability of an overlying base orsub-base course.ENHANCED “SNOWSHOE EFFECT”The greater rib depth and radial stiffnesscharacteristics of TriAx Geogrid are more effective inconfining overlying granular fill than the traditionalTensar BX Geogrids. This mechanism leads to anenhanced “snowshoe effect” over soft subgrades bylocking aggregate particles more efficiently during thecompaction effort. Trafficking trials have verifiedthatTriAx Geogrids outperformed Tensar BX Geogridsthrough this unique feature. This stronger “snowshoeeffect” is even more effective at spreading loads over awider area of subgrade.Just as important, TriAx Geogrid creates an enhanced,mechanically stabilized composite material forconstructing over soft soils. The triangular aperturegeometry more effectively dissipates the radial stressLoad distribution acts radially.Trafficking of TensarBX GeogridTrafficking of TensarTriAx GeogridSubgrade rutting withTensar BX GeogridSubgrade rutting withTensar TriAx Geogrid5

ABSTRACT: Cyclic pUll-out tests were conducted to measure the resistance of geogrids in embankments to dislocation during earthquakes. Two steel boxes were used as soil containers, and a piece of geogrid was laid between the two boxes. The geogrid was pulled out under the following two load conditions: (1) a static overburden pressure .
box pull-out experiments to valid ate the simulation results. They found that the optimum ratio between geogrid aperture size and aggregate size was around 1.4. This paper firstly presents large box pull-out test results with a biaxial geogrid. For the DEM simulations, four different shapes of clumps were used to represent each ballast particle in
