What’s PET Geogrid?

Lianyi® PET Geogrid  is a high strength coated geogrid manufactured from high tenacity polyester(PET) yarns,knitted to form a structured grid.PET Geogrid  is used to reinforce soils where extremely high tensile strength with low elongation is required.The range of PET Geogrid  is from 20kN/m-1000kN/m suitable for solving complex engineering problem.

PET Geogrid strength and stiffness are affected both by temperature and by rate or duration of loading.Therefore,it is important that standard methods of tensile testing are used,so that temperature and strain rate are defined.

PET Geogrid’s tensile strength and high molecular weight offer both vertical and horizontal soil reinforcement,and it’s proprietary UV-stabilized coating compound provides enhanced durability against the elements.

Methodology Of Installation

Road Preparation

Complete crack sealing, pothole filling, base repairs, leveling course application, etc.   

Broad Surface Condition

*Surface must be: dry, clean and dust-free.

*The road surface temperature must be between 5℃ and 60 ℃

*On asphalt surfaces less than 24 hours old, the surface temperature must be between 5℃ & 50 ℃

*Local guidelines should be followed for paving temperature range

Product Preparation

In order to preserve adhesive properties, fiberglass geogrid must be stored inside a dust-free environment and kept dry at the job site. Fiberglass geogrid must not be transported or stored at temperatures greater than 82 ℃  

Methods For Installation

A. With Pressure Sensitive Adhesive

*Load roll onto front or back of tractor. Always load in such a way that allows the placement of mesh with the self-adhesive side down.

*Roll only with a rubber-tired roller to activate adhesive. Roller tyres must be kept clean.

*Apply tack coat/emulsion as per project requirements and pave once cured 

B. Without Pressure Sensitive Adhesive

*Apply the track coat/emulsion in accordance with project specifications.Once the tack coat/emulsion has cured, proceed with the laying of glass fiber grid .

*Load roll onto front or back of tractor.Always load in such a way that allows the placement of glass fiber grid without any wrinkles.

*Roll only with rubber-tired roller and pave the asphalt layer. 

Important Notes

*Because fiberglass geogrid is considered a skin irritant, workers should wear gloves while handling fiberglass geogrid.

*Asphalt Fiberglass grid can be custom cut to fit around structures by using a sharp utility knife.

*Asphalt Fiberglass grid must be applied without ripples. Sufficient tensile strength during application will eliminate this problem. 

*Overlap at end of roll joints 75-100mm. Ensure that the overlaps are shingled in the direction of paving.

*Overlap longitudinal joints 50-75mm.

*Prior to paving, only construction and emergency vehicles shall be allowed to drive on installed asphalt fiberglass grid.

*Damaged sections shall be removed and patched, taking care to underlap the full roll.

*All glass fiber grid placed in a day shall be covered with asphalt immediately, within permissible laying temperatures to a minimum compacted thickness of 40mm.

*Avoid pushing of the asphalt delivery vehicles with the paver, particularly on uphill gradients.

*Prevent asphalt delivery vehicles from executing sharp turns, accelerating or braking on the glass fiber geogrid .
