50kn-50kn Alkali Resistant Asphalt Roadbase PP Bi-axial Geogrid
Product Introduction
PP Bi-axial Geogrid is manufactured from Polypropylene. It is
produced through the process of extruding, punching, heating,
longitudinal stretching and transverse stretching.

PP Bi-axial Geogrid for Road (ground) Base Features:
1. High tension resistance, high plane torsion resistance modulus,
good creep resistance and stable
Chemical nature.
2. High mechanic damage resistance and durability and large
friction factor with sandy stone.
3. It can improve bearing force of foundation (normal improvement
of above 40%) and increase diffusion angle(average increase to 50
degrees from 38 degrees).
4. Under the function of shaft times with same load, it can
decrease 30%-40% of filling thickness for reaching same effect,
when technical grid reinforcement is used, road bed with same
thickness can bear more 3-5 times.
PP Bi-axial Geogrid for Road (ground) Base Application:
1.Reinforcement of road beds of various highways, railways and
airports.
2.Reinforcement of permanent bearing road beds of large parking
area and dock goods yard.
3. Slope protection and culvert reinforcement of railway and
highway.
4. Secondary reinforcement of soil slope after uni-axial tension
technical grid reinforcement
and further reinforcement of soil slope so as to avoid soil
erosion.
5.Reinforcement of mile and gallery.
