DongkaiBiaxial
geogrid (PP)
high strength,erosion resistance,long service
life
Introduction: DongkaiBiaxial
geogrid, made of high molecular
polymer(PP
materials),
extruded into sheet and then punched into regular mesh pattern, and
finally stretched in longitudinal and transverse
directions. For over *0
years, biaxial geogrids have been utilized in pavement construction
and soil stabilization projects throughout the US and
worldwide.Dongkai innovative
geogrid is made from extruded polypropylene which provides superior
stiffness, aperture stability and interlock capabilities for
structural reinforcement of paved and unpaved
roads. Lateral spreading
of base course aggregate or subbase material is the most critical
and common failure in pavement structures.
UsingBiaxial
geogrid stabilizes
aggregate soil through confinement and introduces tensile strength,
and effectively reduces this spreading. It also allows for an
increasing bearing capacity and load support capacity, resulting in
improved structural performance and pavement life. Additionally,
aggregate thickness can be reduced by *0% with the use
ofbiaxial
geogrid. Features: 1. With high
tensile strength in longitudinal and transverse
directions 2.This structure
can provide a chain systemto
provide moreefficient bearing
and spreadingreinforcefor
thesoftsoil. Benefits：
Distribution of
loads and therefore reduction in stress concentration over the
soil.
The geogrids
structural junctions, rigid ribs and thick walls help lock
aggregate, increasing its shear
resistance.
As a result when
a vertical load is applied the aggregate is restrained by the ribs
reducing deformation. (Lateral
Restraint)
Decrease in long
term deformation (creep).
Increase in load
distribution. (Bearing Capacity
Increase)
