- Polypropylene needle-punched non-woven geotextile is primarily employed as the sliding layer between CRTS slab ballastless tracks and beam surfaces on passenger-dedicated railways. It also serves as an isolation layer in various settings and extends its functionality to hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation, and environmental protection fields, where it plays vital roles in isolation, filtration, drainage, reinforcement, and protection.

Geotextile Installation Instructions
How to install geotextile fabric
Explore the simplicity of installing geotextile fabric with our comprehensive guide, enriched with practical tips to enhance your installation experience. In this demonstration,
Step 1 - Prep the road surface
Begin by excavating the roadway to your desired elevation. Ensure optimal compaction of your subgrade, meticulously removing all air to achieve a tightly bound soil base.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully unroll the geotextile fabric over the compacted subgrade, ensuring it lies flat without wrinkles or folds. Adhere to fabric overlap guidelines as specified by your engineer. Cherokee offers pre-sewn fabric options if a stitched seam is required. Reach out to your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the geotextile fabric
For this project, on-site fabric stitching is necessary. Employ a dual thread lock stitch to secure the seams and prevent unthreading. We provide equipment for purchase or rental to execute stitching tasks. Depending on your engineer's discretion, choose from a prayer seam, j-seam, or butterfly seam. In this case, a j-seam is utilized, with a recommendation of double stitching each seam to avert installation failures.
Step 4 - Apply Aggregate
Distribute the aggregate to the prescribed thickness, ensuring no equipment traverses directly on the engineered fill. Confirm full compaction of the fill before proceeding to the final stage.
Step 5 - Lay Asphalt
Now that your subbase is perfectly positioned, you are all set to proceed with the application of your pavement layer (or multiple layers, depending on the intricate demands of your project).

Geotextile Functions Explored
1. Separation Function
The separation function of geotextile plays a critical role, particularly in road construction. It effectively prevents the intermixing of adjacent soils. For instance, by separating the finer subgrade soil from the aggregate base course, geotextile preserves both the drainage efficiency and the inherent strength characteristics of the aggregate material.
Geotextile Applications Include:
- Placement between subgrade and stone base in both unpaved and paved roads, as well as airfields.
- Utilization between subgrade layers in railroad constructions.
- Implementation between landfills and stone base courses.
- Positioning between geomembranes and sand drainage layers.
2. Filtration Expert Functionality
The equilibrium of the geotextile-to-soil system is critical, allowing for sufficient liquid flow while ensuring minimal soil loss across the plane of the geotextile.
Key properties such as porosity and permeability are vital for the geotextile's filtration action.
A typical application demonstrating the filtration function is the inclusion of geotextile in a pavement edge drain, as depicted in the figure above.
3. Reinforcement Capabilities
The inclusion of geotextile in soil structures significantly enhances tensile strength, mirroring the effect of steel reinforcement in concrete. This strength increment is achieved through three primary mechanisms:
- Lateral restraint is provided through interfacial friction between the geotextile and the soil/aggregate.
- It compels the potential bearing surface failure plane to form a higher-strength alternative surface.
- Acts as a membrane support for wheel loads.
4. Sealing Functionality
A non-woven geotextile layer is strategically impregnated between existing and new asphalt layers. The geotextile absorbs asphalt, transforming into a waterproofing membrane that minimizes vertical water infiltration into the pavement structure.
Weight and Environmental Impact Considerations:
Geotextile Advancements: Lightweight nature, which reduces the load on existing structures and significantly lowers environmental impact.
Reinforced Concrete Limitations: Concrete structures are typically heavier, necessitating a more robust foundational base and resulting in a greater environmental impact during production.
Maintenance and Durability:
Geotextile: Geotextiles are designed to require minimal maintenance over time, as they are significantly less susceptible to cracking and deterioration compared to traditional materials. This ensures long-term durability and performance stability, reducing the need for costly and frequent repairs.
Reinforced Concrete: Reinforced concrete structures often demand regular maintenance efforts due to their vulnerability to cracking, corrosion, and numerous other common issues associated with concrete materials. This can lead to increased maintenance costs and a higher frequency of repairs.
Installation time:
Geotextile: The rapid installation process of geotextiles facilitates swift project completion, allowing you to meet your deadlines without compromise. This efficiency in setup not only saves valuable time but also reduces labor costs and accelerates the project's overall timeline.
Reinforced Concrete: The curing period required for concrete can significantly delay project timelines, often impacting set deadlines. This extended time can disrupt scheduling and lead to increased labor costs and logistical complications.
