1.Separation
The separation function of geotextile is majorly used in the construction of roads. Geotextile prevents the intermixing of two adjacent soils. For example, by separating fine subgrade soil from the aggregates of the base course, the geotextile preserves the drainage and the strength characteristics of the aggregate material.
Some of the applicable areas are:
- Between subgrade and stone base in unpaved and paved roads and airfields.
- Between subgrade in railroads.
- Between landfills and stone base courses.
- Between geomembranes and sand drainage layers.
The equilibrium of geotextile-to-soil system that allows for adequate liquid flow with limited soil loss across the plane of the geotextile.
Porosity and permeability are the major properties of geotextiles which involve infiltration action.
A common application illustrating the filtration function is the use of a geotextile in a pavement edge drain, as shown in the figure above.
3.Reinforcement
Introduction of geotextile in the soil increases the tensile strength of the soil the same amount steel does in concrete. The strength gain in soil due to the introduction of geotextile is by the following 3 mechanisms :
- Lateral restraint through interfacial friction between geotextile and soil/aggregate.
- Forcing the potential bearing surface failure plane to develop an alternate higher shear strength surface.
- Membrane type of support of the wheel loads.
A layer of non-woven geotextile is impregnated in between existing and new asphalt layers. The geotextile absorbs asphalt to become a waterproofing membrane minimising vertical flow of water into the pavement structure.
Application
1. Road Work
Geotextiles are widely used in the construction of the road. It reinforces the soil by adding tensile strength to it. It is used as a rapid de-watering layer in the roadbed, the geotextiles need to preserve its permeability without losing its separating functions.
2. Railway Works
The woven fabrics or the non-woven ones are used to separate the soil from the sub-soil without impeding the groundwater circulation where the ground is unstable. Enveloping individual layers with fabric prevents the material from wandering off sideways due to shocks and vibrations from running trains.
3. Agriculture
It is used for mud control. For the improvement of muddy paths and trails those used by cattle or light traffic, nonwoven fabrics are used and are folded by overlapping to include the pipe or a mass of grit.
4. Drainage
The use of geotextiles to filter the soil and a more or less single size granular material to transport water is increasingly seen as a technically and commercially viable alternative to the conventional systems. Geotextiles perform the filtering mechanism for drainages in earth dams, in roads and highways, in reservoirs, behind retaining walls, deep drainage trenches, and agriculture.
5. River, Canals and Coastal Works
Geotextiles protect river banks from erosion due to currents or lapping. When used in conjunction with natural or artificial enrockments, they act as a filter.
Geotextile Installations Instructions
How to install geotextile fabric
Let us show you how easy the installation is and provide a few useful tips along the way. In our example,
Step 1 - Prep the road surface
First, you will need to excavate the roadway to the desired elevation. Then fully compact your subgrade, making sure you have removed all air and tightened the soil completely.
Step 2 - Unroll the reinforcement geotextile fabric
Roll the geotextile fabric on the compacted subgrade, making sure it's free of wrinkles and folds. Overlap your fabric as directed by the engineer. Cherokee can pre-sew the fabric for you if a stitch seam is required. Contact your Cherokee representative to get pricing on factory seamed rolls in a wider widths.
Step 3 - Sew the geotextile fabric
This job required the fabric to be stitched on the job site. The fabric needs to be seamed with a dual thread lock stitch to prevent it from unthreading. We have equipment available for purchase or rental to do the stitching on the job. At the engineers discretion you can choose a prayer seam, j-seam, or butterfly seam. In this example we will be using a j-seam. We recommend doing two stitches on each seam to prevent any failure during installation.
Step 4 - Apply Aggregate
Place your aggregate to the specified thickness, ensuring that no equipment drives directly on the engineered fill. Make sure the fill has reached full compaction before the final step.
Step 5 - Lay Asphalt
Now that you have placed your subbase you are ready for your pavement layer (or layers depending on the project type).
