Reinforce Retaining Wall Road Highway High Strength Tensile HDPE Uniaxial Plastic Geogrid
Uniaxial Plastic Geogrid Introduction
Plastic uniaxial geogrid is manufactured from plastic materials which may be high-density polypropylene or high-density polyethylene (HDPE) resins by the hot extruding process to make the resins into thin plates, the plates are punched into the regular holes for the formation of desired grids, and then the punching patterns are stretched longitudinally into the desired meshes to develop designed tensile strength.

Uniaxial Plastic Geogrid Features
Uniaxial plastic geogrid is specially designed for soil reinforcement. It is manufactured with High Density Polyethylene resins or polypropylene, from the process of extruding and longitudinal stretching. It has high tensile strength, excellent interlock capacity, and low creep deformation. High quality uniaxial plastic geogrid has High tensile strength, good creep performance, convenient construction, low price.
Uniaxial Plastic Geogrid Application
1. Uniaxial plastic geogrid for sale used to reinforce weak foundations.
2. Uniaxial plastic geogrid is used for reinforcing asphalt or cement pavement.
3. Uniaxial plastic geogrid is used to reinforce embankment slope and retaining wall.
4. Uniaxial plastic geogrid is used to reinforce river and sea embankments.
5. Uniaxial plastic geogrid for sale is used to treat landfills.
Construction and laying method
Anchoring method: glass fiber geogrid without self-adhesive can be used to strengthen asphalt concrete pavement and prevent reflection cracks between pavement and pavement. However, it is better to lay glass fiber geogrid first and then spray hot asphalt as bonding oil. Construction personnel must wear gloves. The construction method is as follows:
AH-70 or AH-90 heavy oil hot asphalt shall be selected as tack coat oil. The specification and quality of tack coat oil shall comply with technical specification for construction of highway asphalt pavement (jtj032-94), and special vehicles shall be used for spraying. The amount of tack coat oil per square meter is about 0.4kg-0.6kg.
When laying the glass fiber geogrid, the laying should be smooth and tight. The transverse lap length should be 50-100 mm, and the longitudinal lap length should be 150-200 mm. According to the paving direction, the rear end should be pressed under the front end.
Roll with rubber tyred roller.
The fixed iron sheet of 50? 0? 0? 3 mm should be flat without warping angle, and the surrounding should be chamfered. 2 inch steel nail (high quality cement nail) should be used
When the glass fiber geogrid is laid by nail fixation method, one end of the geogrid is fixed on the lower structure with the asphalt sprayed on it with fixed iron sheet and nails, and the nails can be shot in by hammer or gun. Then the grid will be vertical
