- Polypropylene needle-punched non-woven geotextile is primarily utilized for the sliding layer between CRTS slab ballastless track and beam surface of passenger-dedicated railways, as well as the isolation layer in friction applications of the CRTS system. Beyond railways, it finds extensive use in diverse fields such as hydropower, highways, ports, airports, sports venues, tunnels, beaches, land reclamation, and environmental protection, offering crucial functions like isolation, filtration, drainage, reinforcement, and protection.

Geotextile Installation Instructions
How to install geotextile fabric
We are delighted to guide you through the seamless installation process, complete with insightful tips. In our demonstration,
Step 1 - Prep the Road Surface
Begin by excavating the roadway to the desired elevation. Ensure thorough compaction of the subgrade to eliminate air pockets and achieve maximum soil stability.
Step 2 - Unroll the Reinforcement Geotextile Fabric
Carefully roll out the geotextile fabric over the compacted subgrade, ensuring it remains smooth, without wrinkles or folds. Follow the engineer's guidance for fabric overlap. Cherokee offers pre-sewn options for stitching needs. Contact your Cherokee representative to explore pricing for factory-seamed rolls in wider widths.
Step 3 - Sewing the Geotextile Fabric
For this task, the fabric requires on-site stitching. Utilize a dual-thread lock stitch method to ensure durability and prevent unraveling. Equipment for purchase or rental is available for on-the-job stitching. Depending on engineering preferences, choose between prayer, j-seam, or butterfly seam options. Our example utilizes a j-seam, with two stitches per seam recommended for optimal installation integrity.
Step 4 - Apply Aggregate
Distribute the aggregate to the specified thickness, ensuring no equipment traverses the engineered fill directly. Verify full compaction of the fill before proceeding to the final stage.
Step 5 - Lay Asphalt
Having completed the subbase installation, you are now poised to embark on the paving layer process, which may involve multiple layers depending on the specific requirements of your project.

Geotextile Functionalities
1. Separation
The separation capability of geotextiles is primarily utilized in road construction. It prevents the mixing of distinct soil layers, maintaining drainage and strength by separating fine subgrade soil from the aggregate in the base course.
Geotextiles find application in areas such as:
- In between subgrade and stone base layers in both unpaved and paved roads and airfields.
- Positioned between subgrade layers within railroad tracks.
- Installed between landfill sites and stone base courses.
- Used between geomembranes and sand drainage layers.
2. Filtration
Geotextiles achieve an equilibrium in the soil system, allowing for adequate liquid permeability while limiting soil loss.
Key attributes such as porosity and permeability are integral to geotextiles' infiltration function.
An exemplary application showcasing filtration is the use of geotextile in pavement edge drains.
3. Reinforcement
Embedding geotextile within the soil enhances tensile strength, akin to steel reinforcement in concrete, through these mechanisms:
- Providing lateral restraint via interfacial friction between geotextile and soil/aggregate.
- Encouraging the potential bearing surface to develop an alternative surface with higher shear strength.
- Offering membrane-like support to withstand wheel loads.
4. Sealing
Non-woven geotextiles, when impregnated between asphalt layers, act as a waterproofing membrane that minimizes water penetration into pavement structures.
Weight and Environmental Considerations:
Geotextile Advantages: Geotextiles are lightweight, reducing stress on existing structures and contributing to a lower environmental footprint.
Reinforced Concrete: Concrete structures, while strong, inherently possess a heftier nature. This demands a more substantial foundational base, and concurrently, contributes to a heightened environmental footprint during production. The weight and environmental strain of concrete cannot be overstated, presenting significant challenges in sustainable construction practices.
Maintenance and Enduring Durability:
Geotextile: Innovative Solutions for Longevity Geotextiles require minimal maintenance over the years, as they adeptly resist cracking, wear, and the typical deterioration that plagues other materials. This robustness translates to long-term cost savings and peace of mind, making geotextiles a superior choice for sustainable infrastructure.
Reinforced Concrete: Maintenance Challenges Concrete structures often necessitate regular upkeep due to prevalent issues such as cracking, corrosion, and an array of other typical structural problems. These vulnerabilities can escalate into significant maintenance demands.
Efficiency in Installation Time:
Geotextile: Swift and Efficient Deployment The rapid installation process of geotextiles enables project completion at an accelerated pace, significantly enhancing project efficiency and meeting tight deadlines with ease.
Reinforced Concrete: Potential Delays The requisite curing period of concrete can extend project timelines, potentially impacting planned completion dates and influencing project success.
