- The versatile polypropylene needle-punched non-woven geotextile serves primarily as a sliding layer between the CRTS slab ballastless track and beam surface, and as an isolation layer between CRTS slab track and friction zones. Beyond railways, it finds extensive utility in hydropower, highways, ports, airports, sports venues, tunnels, beaches, reclamation projects, environmental protection, and more. It excels in roles like isolation, filtration, drainage, reinforcement, and protection across these diverse fields. Technical Data
Geotextile Installations Instructions
How to install geotextile fabric
Experience the simplicity of installation with our geotextile fabric, as we guide you through the process with helpful tips and expert advice. In our demonstration,
Step 1 - Prep the road surface
Begin by excavating the roadway to your desired elevation. Follow this by thoroughly compacting your subgrade, ensuring all air pockets are eliminated and the soil is tightly compacted to perfection.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully unroll the geotextile fabric over the compacted subgrade, ensuring it's smooth, without wrinkles or folds. Overlap the fabric as per engineer instructions. For seamless integration, Cherokee can pre-sew the fabric for you if a stitch seam is necessary. Reach out to your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the geotextile fabric
In this task, the fabric requires on-site stitching. Employ a dual-thread lock stitch to secure it firmly. We offer equipment for purchase or rental to assist with on-site stitching. Depending on engineering specifications, choose from prayer seam, j-seam, or butterfly seam. For this instance, we demonstrate the j-seam technique, with double stitching on each seam, ensuring robust installation integrity.
Step 4 - Apply Aggregate
Distribute the aggregate to meet the specified thickness, ensuring no equipment traverses over the engineered fill. Verify that the fill has achieved complete compaction before proceeding to the final step.
Step 5 - Lay Asphalt
With your subbase perfectly in place, venture confidently into the next phase—laying your pavement layer or layers, tailored to suit your specific project requirements.

Essential Geotextile Functions
1. Separation
In road construction, geotextile's separation function prevents the mingling of different soil types. By keeping fine subgrade soil apart from base course aggregates, it maintains drainage and the aggregate's strength characteristics.
Geotextile is applicable in areas such as:
- Between subgrade and stone base in both unpaved and paved roads and airfields.
- Between subgrade layers in railroads.
- Between landfills and stone base courses.
- Between geomembranes and sand drainage layers.
2. Filtration
Geotextiles achieve a balance in the geotextile-to-soil system, ensuring efficient liquid flow while limiting soil loss across the geotextile's surface.
Porosity and permeability are key geotextile properties driving its infiltration capabilities.
A typical filtration application includes using geotextile in pavement edge drains, enhancing drainage efficiency.
3. Reinforcement
Introducing geotextile into soil significantly boosts tensile strength, much like how steel reinforces concrete. This strength enhancement occurs through three mechanisms:
- Lateral restraint via interfacial friction between geotextile and soil/aggregate.
- Encouraging the development of an alternative failure plane with higher shear strength.
- Providing membrane-type support for wheel loads.
4. Sealing
Impregnated non-woven geotextile between old and new asphalt layers forms a waterproof membrane, minimizing vertical water flow within the pavement.
Weight and Environmental Impact Consideration:
Geotextile Advantages: Lightweight geotextiles reduce load on existing structures and diminish environmental impact.
Reinforced Concrete Notes: Concrete structures inherently possess significant mass, necessitating a more formidable foundation. This results in a heightened environmental footprint during their production process.
Maintenance and Durability:
Geotextile: Geotextiles demand minimal upkeep over time, as they are resistant to common issues such as cracking and degradation.
Reinforced Concrete: Reinforced concrete structures frequently demand ongoing maintenance due to issues like cracking, corrosion, and other prevalent concrete-related problems.
Installation time:
Geotextile: Efficient and rapid installation accelerates project timelines, allowing for quicker completion.
Reinforced Concrete: The curing period of concrete can extend project timelines significantly, potentially affecting critical deadlines.
