  Soil Reiforcement Geogrid  Introduction

Soil Reiforcement Geogrid  belong to geosynthetics materials that fulfil a reinforcing function in a ground structure. They are formed by a flat polymer structure, namely by a system of mutually perpendicular longitudinal and cross drawn elements which can be bonded continually by weaving, welding, gluing or binding in the points of intersection thus usually creating apertures with sizes between 1 and 10 cm.

This allows penetration of particles of soil/rock or other geotechnical materials through mesh apertures and formation of particle interlocking. It is good for this reinforcing particle interlocking effect when the grains are able to push through the mesh with at least a half of their volume into the substrate layer.

Soil Reiforcement Geogrid are used both for reinforcement of non-cohesive, cohesive soils and formation made of coarse-grained materials.
Mining Roof Support Geogrid   are classified as uniaxial and biaxial grids
Uniaxial grid - strength in the machine direction of reinforcement is predominant
Biaxial grid - strengths in the cross and machine directions of the geogrid are equal

 

Soil Reiforcement Geogrid Application:

 

 

The following are the main applications where Soil Reiforcement Geogrid are used:

 

Unpaved roads and Temporary Working Surfaces

 

The required thickness of an unpaved road or working surface is principally a function of the traffic intensity it experiences (magnitude of axle load, number of vehicle passes, etc.) and the shear strength of the underlying subgrade – more intense traffic and weaker subgrades requires thicker aggregate layers.

 

For a given set of design conditions, the use of a biaxial geogrid reduces the required aggregate thickness by up to 60%. This results in:
• Initial cost savings typically in the range of 40-50%.
• Faster construction.
• More environmentally friendly or “greener” construction methods – 20 to 40% reduction in the carbon emissions associated with the road construction.

 

Conventional and Heavy-duty Pavements

 

The same principles apply for both flexible and rigid pavements which incorporate a granular layer within the main pavement structure. Biaxial geogrids are typically used to provide one of the following benefits:
• Optimize the pavement section to provide maximum initial cost savings – typically 10-20%
• Keep an existing pavement design but “beef it up” with a geogrid to extend its design life – typically 2- to 6-fold.
