- The polypropylene needle-punched non-woven geotextile primarily serves as a sliding layer between CRTS slab ballastless track and the beam surface of passenger dedicated railways. It also acts as an isolation layer between CRTS slab ballastless track and friction. Its versatility extends to fields such as hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation, and environmental protection, offering roles in isolation, filtration, drainage, reinforcement, and protection.

Geotextile Installation Instructions
How to install geotextile fabric
Discover how straightforward geotextile installation can be, enhanced with valuable tips along the way. In our guide, you'll find expert advice and insights to ensure seamless application.
Step 1 - Prep the Road Surface
Begin by excavating the roadway to the desired elevation. Ensure the subgrade is fully compacted, removing all air and tightening the soil completely to set a strong foundation.
Step 2 - Unroll the Reinforcement Geotextile Fabric
Carefully roll the geotextile fabric onto the compacted subgrade, ensuring it remains smooth and wrinkle-free. Overlap the fabric as specified by the engineer. Cherokee can pre-sew the fabric for you if a stitch seam is necessary. Contact your Cherokee representative to inquire about pricing on factory-seamed rolls in wider widths.
Step 3 - Sewing the Geotextile Fabric
For this project, on-site stitching of the fabric is required. Use a dual-thread lock stitch to prevent unthreading. Equipment for this purpose is available for purchase or rental. According to the engineer's discretion, you may select from prayer seam, j-seam, or butterfly seam, with this instance utilizing a j-seam. We recommend dual stitching on each seam to ensure a robust installation.
Step 4 - Apply Aggregate
Distribute the aggregate to the prescribed thickness, ensuring no equipment drives directly on the engineered fill. Confirm the fill has achieved full compaction before proceeding to the final step.
Step 5 - Lay Asphalt
With your subbase firmly in place, you are now ready to proceed to the next pivotal phase of your construction project—the laying of your pavement layer, tailored to fit the unique demands and multiple layers of your specific project requirements.

Key Functions of Geotextile
1. Separation
The separation function of geotextiles is critically employed in road construction. It acts as a barrier, preventing the intermixing of neighboring soils. For instance, it separates the fine subgrade soil from the coarse aggregates of the base course, thereby maintaining the drainage efficiency and strength properties of the aggregate material.
Prime Areas of Application:
- Applications between subgrade and stone base in both unpaved and paved roads, as well as in airfields.
- Implementations between subgrade layers in railroad constructions.
- Utilizations between landfills and stone base courses.
- Applications between geomembranes and sand drainage layers.
2. Filtration
Geotextiles achieve equilibrium in the soil-to-textile system, permitting sufficient liquid flow while minimizing soil loss across the plane of the geotextile.
Porosity and permeability are critical properties of geotextiles that facilitate effective infiltration and filtration.
A typical example of the filtration function is the use of geotextiles in a pavement edge drain, as illustrated in our figure.
3. Reinforcement
Integrating geotextiles into soil structures enhances soil tensile strength akin to steel reinforcement in concrete. The increase in soil strength is achieved through three primary mechanisms:
- Providing lateral restraint through interfacial friction between geotextile and soil/aggregate.
- Compelling the potential failure plane to develop along an alternative, stronger shear surface.
- Supporting wheel loads through a membrane action.
4. Sealing
A layer of non-woven geotextile is embedded between existing and new asphalt layers, absorbing asphalt to form a waterproofing membrane that prevents vertical water penetration into the pavement structure.
Weight Considerations and Environmental Impact:
Geotextile Advantages: Our geotextiles are lightweight, reducing the load on existing structures and lessening environmental impact.
Reinforced Concrete Considerations: Concrete structures, recognized for their substantial weight, inherently demand a more fortified foundation. This heft, coupled with the production process, leads to a significant environmental footprint.
Maintenance and Durability: A Comparative Analysis
Geotextile: An Innovative Solution These materials necessitate minimal maintenance over time, as they exhibit remarkable resistance to cracking and wear. This longevity ensures cost-effectiveness and sustainable performance.
Reinforced Concrete: Traditional Yet Demanding This type of structure often requires ongoing maintenance due to its susceptibility to cracks, corrosion, and other prevalent issues, leading to increased long-term costs.
Installation Time: Efficiency Matters
Geotextile: Fast and Efficient With their rapid installation process, geotextiles enable projects to be completed swiftly, optimizing both time and resources.
Reinforced Concrete: Time-Intensive Process The necessity for concrete curing can extend the timeline for project completion, potentially affecting adherence to schedules and increasing overall project duration.
