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 .
