TGSG30-30 Type ASTM D4595 Standard 100m Length highway Asphalt Geogrids Asphalt Geogrids Introduction: Triaxial Geogrid TriAx® (TX) geogrids, a next-generation enhancement to biaxial geogrids, have additional diagonal ribs that increase the product's in-plane stiffness. The triangular pattern is formed into a hexagon to improve how the product absorbs traffic loading forces. TriAx® creates a more efficient effect that delivers optimal in-service stress transfer from the aggregate to the geogrid. Triaxial geogrids have undergone extensive full-scale and field testing and have been calibrated within the more common pavement design methodologies, both for paved and unpaved roads.
The properties of Biaxial Geogrids, made of Polypropylene (PP) with their square apertures, high tensile strength and optimised geometry of nodes and ribs make them equal to any other similar material. The reinforcing action of PP Biaxial Geogrids lies mainly in confining soil and increasing its shearing resistance by a process of interlocking between the square ribs and the soil. The load dispersal effect from the interlocking mechanism is highly effective and can reduce sub-base thickness and construction cost. PP Biaxial Geogrids can be used with any kind of mechanical fill material. Two aperture size ranges are available for optimum matching with project fill.
What are geogrids? By now, you have probably read or heard about the multiple benefits of using geogrids in various types of civil engineering construction applications. The two most significant are the improvement of your construction project's speed and the reduction of your overall cost. But you might still be asking yourself, what exactly are geogrids and how do they create an impact on my bottom line and project's success? What is a geogrid? A geogrid is defined as a geosynthetic material consisting of connected parallel sets of tensile ribs with apertures of sufficient size to allow strike-through of the surrounding soil, stone, or other geotechnical material (Qijie Company). Geogrids provide reinforcement, stabilization, and even filtration when used with properly sized aggregate fills. Made from polymers such as polypropylene, polyethylene, or polyester, they are used widely in civil engineering applications. Geogrids are deployed for three primary applications: 1. Building firm working surfaces over soft ground conditions 2. Enhance a pavement's service life 3. Reduce the structural cross-section of both paved and unpaved roadways for given service life. Geogrids have also been proven to significantly improve a pavement's susceptibility to environmental cracking common when building over highly expansive subgrade soils. Geogrids work by interlocking with the granular or soil material placed over them. The open apertures of the geogrid allow for the confinement of material within, increasing the shear strength of overlying granular fill. The different types of geogrids? There are four types of geogrids Uniaxial, Biaxial, Triaxial (Triax®) and Geogrid-Geotextile Composites. Each designed and manufactured for specific construction applications with various geometric and structural index properties. Biaxial Geogrid Biaxial (BX) geogrids are stretched in two directions, the longitudinal and transverse, equally distributing stress along both directions. While woven geogrids are still commercially available, extruded punched-and-drawn geogrids made of polypropylene are the most deployed among biaxial geogrids. Providing the geogrid with the ability to distribute loads over a wider area than usual while increasing its capacity in base stabilization applications. Biaxial geogrids are best for applications such as foundations for roadbeds, railroad truck beds, permanent unpaved roads, airport runways, construction haul roads, working platforms on weak subgrades, and parking lots. Uniaxial Geogrid Certain Uniaxial (UX) geogrids are oriented along the longitudinal, "machine direction" of an extruded sheet of polymer, thus yielding a grid structure consisting of long narrow ribs. Other products utilize polyester yarns to render extremely high allowable strengths at deficient strains. Given their unique properties, Uniaxial geogrids are ideal for both wall and slope applications such as retaining walls, landfill liner systems, embankments over soft soils, and very steep earthen slopes.

-
Optimize the pavement section to provide maximum initial cost savings: typically 10% - 20% -
Maintain an existing pavement design but “beef it up” with a geogrid to extend its design life: typically 2-to-6 fold -
Develop a cost-neutral solution, i.e., provide some design life extension while ensuring there is no additional cost resulting from the use of the geogrid Uniaxial Geogrid are highly resistant to installation damage and long-term chemical/biological deterioration because they are created from exclusive grades of high-density polyethylene (HDPE) resins. Due to the inert properties of HDPE resins, Uniaxial Geogrids have shown no degradation in materials with pH levels as high as 12. This means they can be installed with a variety of backfill materials including recycled concrete and on-site soils.
