Prevent Cracking Asphalt Driveway Coated Bitumen Fiberglass Geogrid 50 50 Grid

Product Specification

Prevent Cracking Asphalt Driveway Coated Bitumen Fiberglass Geogrid 50 50 Grid Mesh 25.4mm

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.

How Fiberglass Geogrid Fights Prevent Cracking Asphalt Driveway ?

A fiberglass geogrid doesn't make the asphalt "stronger" in a simple sense.

Instead, it functions through mechanically interlocking with the asphalt and absorbing stress:

1>  Stress Relief Membrane:

The geogrid is placed between the old pavement and the new asphalt. Its high tensile strength allows

it to absorb the tensile stresses caused by the movement of the old cracks.

2> Interlock with Asphalt:

The hot asphalt mix passes through the grid's apertures during paving, locking it firmly in place.

This creates a reinforced composite layer.

3> Reduces Stress Concentration:

When the old crack tries to move, the geogrid bridges the crack and spreads the stress over a wider area,

preventing it from concentrating into a single point strong enough to break the new asphalt surface.

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.
