Ultimate Tensile Strength 100KN/M Woven Coated Bitumen Fiberglass
Geogrid Reflective Cracking Asphalt Driveway
Fiberglass Geogrid 100 100 Key Characteristics and Advantages:
Fiberglass Geogrid 100-100 is a workhorse material in geotechnical
engineering.
It's a biaxial, high-strength, and durable grid used to make soil
stronger, stabilize weak ground,
and create longer-lasting, more cost-effective paved areas by
improving the performance of the aggregate layers
How Fiberglass Geogrid Reflective Cracking Happens ?
1.An existing concrete slab or old, cracked asphalt driveway
develops cracks.
2.These cracks move due to thermal expansion/contraction
(temperature changes) and traffic loading.
3.When you pave a new layer of asphalt over it, these movements in
the old layer transfer upward through the new, weak layer.
4.Within a short time (often just one or two seasons), the exact
same crack pattern appears in your brand new driveway.
What Means Fiberglass Geogrid Tensile Strength 100KN/M ?
- 100-100: This is the most important part of the specification.
It denotes the minimum ultimate tensile strength per unit width in
the machine direction (MD)
and cross-machine direction (CMD), measured in kN/m (kiloNewtons
per meter).
- The first 100 means it has a minimum ultimate tensile strength of
100 kN/m in its longitudinal direction (along the roll length).
- The second 100 means it has a minimum ultimate tensile strength of
100 kN/m in its transverse direction (across the roll width).
In short, Fiberglass Geogrid 100-100 is a biaxial (equally strong
in both directions) geogrid made from fiberglass,
with a strength rating of 100 kN/m.

Key Benefits:
✔ Optimal Load Distribution – Reduces stress and prevents
reflective cracking
✔ Asphalt-Compatible – Bitumen-coated for superior adhesion in
paving applications
✔ High Tensile Strength – 50 kN/m in both directions (longitudinal
& transverse)
✔ Corrosion & UV Resistant – Long-lasting durability in harsh
conditions
✔ Easy Installation – Flexible, lightweight, and roll-form for
quick deployment
Fiberglass Geogrid 100 100 Applications:
This specific strength (100-100) is very common and versatile. Its
main uses include:
Road and Pavement Reinforcement:
Laid on soft subgrade before placing the aggregate base course.
It reduces rutting, extends pavement life, and allows for a thinner
base layer, saving cost.
Soil Stabilization: Used to build stable working platforms on very
soft soils (like clay or peat),
allowing construction equipment to operate.
Asphalt Overlay Reinforcement:
A specialized application where a fiberglass geogrid is embedded in
asphalt to retard reflective cracking from old pavement layers.
Landfill and Embankment Support: Provides tensile strength to soil
structures.
Parking Lots and Access Roads: A very common application for this
strength class.
Fiberglass Geogrid Reflective Cracking Conclusion:
Using a fiberglass geogrid for reflective cracking is a proven,
engineered solution that can
significantly extend the life of an asphalt overlay on a cracked
driveway.
It is not a DIY-friendly product and its success is 100% dependent
on correct installation
by a knowledgeable asphalt paver. When done right, it is one of the
most effective ways
to prevent your old driveway's problems from haunting your new one.
