POLYPROPYLENE SHORT FIBER NEEDLE PUNCHED GEOTEXTILE
Crafted using ultra-high-strength polypropylene staple fiber or ES fiber as the core raw material, this product is engineered through cutting-edge non-woven technology. It excels in offering isolation, reinforcement, protection, filtration, drainage, and buffering functions.
Product specifications: PP100~PP1200, width ranges from 2m to 6m. Customizable length to meet specific user requirements.
Boasting physical and mechanical properties 2 to 3 times superior to conventional products, our geotextile is lightweight despite its gram weight. It displays excellent acid and alkali resistance, robust hot melt adhesion, and superior wear resistance. This makes it an ideal choice for CRTS/slab ballastless track sliding layer systems, significantly minimizing interaction between track systems and bridge surfaces.

- The polypropylene needle-punched non-woven geotextile primarily serves as a sliding layer between CRTS slab ballastless tracks and beam surfaces in passenger-dedicated railways. It also functions as an isolation layer between CRTS slab ballastless tracks and friction surfaces. Its versatility extends to hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation, and environmental protection projects, where it provides isolation, filtration, drainage, reinforcement, and protection.

Geotextile Installation Instructions
How to install geotextile fabric
Discover how effortlessly you can install geotextile fabric with our step-by-step guide, enriched with practical tips along the way. Let's begin:
Step 1 - Prep the road surface
Start by excavating the roadway to your desired elevation. Ensure the subgrade is completely compacted by eliminating air pockets and tightening the soil to perfection.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric over the compacted subgrade, ensuring a smooth layout free of wrinkles and folds. Overlap the fabric as per the engineer's guidance. Cherokee can pre-sew the fabric for you if stitching is necessary. Reach out to your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the geotextile fabric
This installation requires the fabric to be stitched on-site. Use a dual-thread lock stitch to seam the fabric and prevent unthreading. We provide equipment for purchase or rental to facilitate this process. Depending on the engineer's preference, choose from a prayer seam, j-seam, or butterfly seam. In this illustration, a j-seam is employed. For optimal results, execute two stitches on each seam to ensure stability during installation.
Step 4 - Apply Aggregate
Distribute the aggregate to the specified thickness, taking care to prevent equipment from driving directly on the engineered fill. Confirm that the fill achieves full compaction before proceeding to the final step.
Step 5 - Lay Asphalt
You've successfully laid your subbase, setting the stage for the next step: the pivotal pavement layer. Depending on the specifics of your project, this may involve one layer or several, each crucial in creating a robust and durable surface.

Geotextile Features
1. Separation
Geotextiles are essential in road construction for their separation capabilities, preventing the intermixing of two different soils. This process is crucial in maintaining drainage and the strength characteristics of the base aggregate by separating fine subgrade soil from it.
Some Key Application Areas Include:
- Placement between subgrade and stone base in both paved and unpaved roads and airfields.
- Used between subgrade layers in railway constructions.
- Implemented between landfill sites and stone base courses.
- Applied between geomembranes and sand drainage layers for optimal performance.
2. Filtration
Geotextiles are pivotal in maintaining the soil-geotextile equilibrium, allowing liquid to flow effortlessly while limiting soil loss across the geotextile plane.
Porosity and permeability are the defining properties of geotextiles, facilitating effective infiltration.
A common demonstration of geotextile filtration is its use in pavement edge drains, an illustration of its efficiency.
3. Reinforcement
Geotextiles enhance soil tensile strength much like steel does for concrete, providing reinforcement through: lateral restraint with geotextile-soil friction, enforcing a stronger failure plane, and supporting wheel loads as a membrane.
- Lateral restraint via interfacial friction between geotextile and soil/aggregate.
- Facilitating an alternative, higher shear strength surface for potential bearing failure planes.
- Membrane-like support distributed over wheel loads.
4. Sealing
When integrated between existing and new asphalt layers, non-woven geotextiles absorb asphalt, transforming into a waterproofing membrane that effectively restricts water infiltration into the pavement structure.
Weight and Environmental Contributions:
Geotextile Benefits: Lightweight construction minimizes load on existing structures and reduces environmental footprint.
Reinforced Concrete Considerations: Concrete structures are inherently heavier, requiring sturdier bases and contributing to greater environmental impact during manufacturing.
Maintenance and Durability:
Geotextile: Geotextiles are a marvel of low-maintenance engineering, designed to resist cracking and deterioration, ensuring longevity and reliability with minimal upkeep.
Reinforced Concrete: Reinforced concrete structures, while robust, can be susceptible to common issues like cracks and corrosion, necessitating regular maintenance to uphold their integrity and functionality.
Installation time:
Geotextile: Experience the efficiency of swift geotextile installation, enabling you to expedite project timelines and achieve completion at a remarkable pace.
Reinforced Concrete: The extended concrete curing process can delay project timelines, potentially impacting critical deadlines and overall progress.
