Soil stabilization can be achieved through various methods, including reinforcement with geotextiles (Vimal et al., 2023) , planting
compactors. The use of geotextiles in soil stabilization typically involves rolling the material over the intended area, securing it in place, and then layering it on suitable fill or aggregates. [...] There may be more than one way to get a job done, but that doesn’t mean one is as good as another. Given the circumstances of your project and your job site, there may be one technique that brings superior results. For example, stabilizing soils is critical for ensuring your work has a strong foundation. Two of the most common methods are chemical soil stabilization and geotextile fabric for soil stabilization. The former uses the application of chemical reagents to strengthen soils, while the [...] Chemical methods of stabilizing soils are used in a broad range of applications. These include practically any type of construction project involving hard surface paving or structural fill zones. By comparison, soil stabilization by geotextiles and fabrics is frequently employed to create retaining walls, reinforce slopes and embankments, or bridge over subgrades too weak to support an aggregate base. ## PROS AND CONS
Geotextiles, made from polypropylene or polyester, are permeable fabrics used in soil stabilization since the 1970s, aiding in tasks like separation, filtration, reinforcement, and drainage. They come in woven, non-woven, and knitted forms, each serving distinct functions such as erosion control and improving bearing capacity in pavements. The document discusses various tests and applications to enhance soil strength and integrity using geotextiles.

Geotextiles for soil stabilization 2 Geotextiles
Geotextiles, geogrids, steel fibers, etc. are some types of geosynthetics which helps to distribute the loads on pavement structure more efficiently. According to studies, it improves the soil subgrade's effective bearing capacity and serves as an alternate method of economic stability. Geotextile may also be used as reinforcement in asphalt overlays to mitigate the reflection cracking. Geotextiles also aid in enhancing the base course'sflexural stiffness, which lowers the maximum vertical load [...] plasticity index and a high moisture content that can reach more than 50%. Researchers have historically used these three methods to combat the issue: remove a portion of the soil; combine materials as soil cementitious with the soil; and raise the thickness of the base course or asphalt layer. Subgrade stabilization's major goals are to lessen rutting, stiffen the subgrade, and distribute load more evenly in order to prevent differential settlement. [...] this interaction stability. Under the geosynthetics, the second process stabilizes the subgrade soil. This shows that local punching or shear failure is avoided while the soil is loaded from the top and held in place. About 80% more loading may be applied to the soil before its strength is reached thanks to the shift from local to general shear in the soil's failure mode . This process enables a smaller structural section to be placed over a subgrade that has been geotextilally stabilized. The
###### Geotextiles Geotextiles are fabrics that resist chemicals and biodegradation. Like bitumen, geotextiles mechanically interact with the soil to provide increased strength and bearing capacity. Opening size, interlocking grab strength, and puncture resistance are important factors associated with geotextiles. The increased cost of geotextiles adds to the overall cost of the project. ###### Grout [...] Soil stabilization can improve in situ, or natural state, soils eliminating the need for expensive remove-and-replace operations. Often job sites where roads, building pads, parking lots, runways or other pavement structures need to be built contain naturally wet, weak soils. Those soils can be chemically treated to add strength through stabilization and improve engineering properties including moisture content and plasticity, through modification. Ex situ, or off site, soil stabilization [...] Soil stabilization is a process by which the physical properties of a soil are transformed to provide permanent strength gains before construction. Stabilized soils outperform non-stabilized soils when materials, design, and construction are properly considered. When the stabilized soil layer is incorporated into the structural design of the pavement, the subsequent layers can be thinner, resulting in sizable cost savings and minimizing the need for virgin materials. In addition to adding
Geotextiles are permeable fabrics that separate, filter, and reinforce soil for erosion control and drainage. Geogrids are flat, grid-like structures that reinforce soil by distributing loads, common in road bases and retaining walls. Geocells are 3D, honeycomb-like structures that confine and stabilize soil, ideal for slope stabilization and intense erosion control. [...] Just like clothing or linens, you can categorize geotextiles by how they’re made: woven, nonwoven, or knitted. The manufacturing method may not seem like a big deal, but it’s crucial because it determines the types of projects on which each geotextile performs best. #### Woven Geotextiles [...] ## Conclusion Geotextiles, geogrids, geocells, and geomembranes serve distinct roles in soil stabilization and construction. Let’s recap:
The knitted geotextile's fabric structure allows for interaction with the surrounding soil by creating friction and preventing it from moving or sliding.
