Uni-axial Geogrid for Road (ground) Base Description：

Unidirectional plastic technical grid is a kind of technical material with high strength that uses high molecular polymer as

main raw material, adds certain ultraviolet proof and aging resistance agent and makes messy chain shape molecules have

directional layout and from linear status by unidirectional extension. Plastic technical grid makes directional tension under

certain temperature condition according to physical features of high molecule polymer,so its strength is very high in tension

direction,tension resistance reaches 100-200Mpa, yield elongation rate is only 4-10%, it is near to the level of low carbon steel

and much better than traditional or current reinforcement materials, and is very ideal synthetic material for strengthening and

reinforcement of civil projects.

Uni-axial Geogrid for Road (ground) Base Feature：

1,High  unidirectional tension  resistance,   good  creep  resistance  and  stable  chemical  nature.

2,It  has  large  friction  factor  with  sandy  stone.

Uni-axial Geogrid for Road (ground) Base Application：

1,It  is  mainly  used  in  retaining  wall,  bridge  abutment,  steep  slope  project  and  so  on.

2,Retaining  wall  and  bridge  abutment  belong  to  force  bearing  structures  and  bear  all external  loads  such  as  active  soil  pressure,  support  of  structure  upper  part  and  temperature  stress,  under  the  function  of  large  tension  and  repeated  function  of  dynamic  load  ,molecule  structure  of  reinforcement  material  occurs  fatigue,  its  performance  occurs attenuation  and  aging  of  grid  quickens.   In  order  to  avoid large  deformation  of  structure  caused  by  creep  of  reinforcement  material,  unidirectional  technical  grid  with  high-density  polyethylene (HDPE)  as   raw  material  shall  be  used.

PP Bi-axial Geogrid for Road (ground) Base Description：

  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：

• High tension resistance, high plane torsion resistance modulus, good creep resistance and stable

Chemical nature.

• High mechanic damage resistance and durability and large friction factor with sandy stone.
• It can improve bearing force of foundation (normal improvement of above 40%) and increase diffusion angle（average increase to 50 degrees from 38 degrees).
• 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.
