Fiberglass Geogrid

Fiberglass geogrid is woven from high-strength glass fiber rovings into an open-mesh grid and finished with a bitumen or polymer coating. With tensile strength of 30–100 kN/m and elongation at break of no more than 4%, it provides the highest modulus-to-strain ratio among common reinforcement geogrids — precisely the property asphalt overlays demand.

Its best-proven application is asphalt pavement reinforcement and reflective cracking prevention. Placed at the bottom of an asphalt overlay, the fiberglass geogrid for asphalt pavement absorbs and distributes stress concentrations rising from joints and cracks in the old pavement, delaying crack propagation to the new surface and extending overlay life by a factor of 1.5–3.

Glass fiber is dimensionally stable at asphalt paving temperatures and chemically inert in the presence of bituminous binders. The bitumen-coated mesh bonds integrally with the hot mix asphalt layer, preventing slippage and rutting at intersections, bus lanes and heavy-duty industrial pavements exposed to braking and turning forces.

Typical projects include highway and airport pavement rehabilitation, bridge deck waterproofing overlays, and old concrete road reconstruction before asphalt resurfacing. Standard mesh sizes are 12.7 mm and 25.4 mm, with roll widths of 1.0–2.0 m to suit paver widths; all products are tested to ASTM D6637 and JTG E50.

As a fiberglass geogrid factory in China, we supply both bitumen-coated and polymer-coated versions, with custom mesh sizes, strengths and roll dimensions for distributors and contractors.
