Geogrid Biaxial Geogrid Introduction: Biaxial GeogridBiaxial (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.
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 conditions2. Enhance a pavement's service life3. 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. Uniaxial GeogridCertain 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. Triaxial GeogridTriAx® (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.
