POLYPROPYLENE SHORT FIBER NEEDLE PUNCHED GEOTEXTILE

• Product Introduction:

Using ultra-high-strength polypropylene staple fiber or ES fiber as the main raw material, it is produced by non-woven technology and has the functions of isolation, reinforcement, protection, filtration, drainage, and buffering.
Product specifications: PP100~PP1200, width 2m~6m., length according to user requirements.

• Features:

The physical and mechanical properties are 2 to 3 times higher than that of conventional products. The proportion of products with the same gram weight is low; the acid and alkali resistance is excellent, the hot melt adhesion is good, and the wear resistance is strong. It is more suitable for CRTS/ slab ballastless track sliding layer system, which can reduce the interaction between the track system and the bridge surface.

• Polypropylene needle-punched non-woven geotextile is mainly used for the sliding layer between CRTS slab ballastless track and beam surface of passenger dedicated railway, and the isolation layer between CRTS slab ballastless track and friction. It can also be widely used Hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation, environmental protection and other fields play the role of isolation, filtration, drainage, reinforcement, protection, etc. Technical Data

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).

Geotextile function





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.

2.Filtration
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.

4. Sealing                                                                          
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.


 

 

Weight and Environmental Impact:
Geotextile: They are light, minimizing the load on the existing structure and reducing the environmental impact.
Reinforced Concrete: Concrete structures tend to be heavier, requiring a more robust base and generating greater environmental impact during production.

Maintenance and Durability:
Geotextile: Require less maintenance over time as they are less prone to cracking and deterioration.
Reinforced Concrete: May require regular maintenance due to cracks, corrosion and other common problems in concrete structures.

Installation time:
Geotextile: Quick installation allows you to complete projects faster.
Reinforced Concrete: Concrete curing time can prolong project completion, impacting deadlines.
