Geotextiles play a crucial role in modern geotechnical engineering. These permeable fabrics, typically made from synthetic materials like polyester or polypropylene, are incorporated into various soil improvement strategies. They provide reinforcement, separation, filtration, and drainage functions, significantly enhancing the stability and performance of earthworks. Geotextiles can be utilized in a wide range of applications, including road construction, embankment stabilization, soil erosion control, landfill design, and drainage systems. By effectively modifying soil properties and improving inter-particle interactions, geotextiles contribute to the longevity of infrastructure projects, minimizing maintenance requirements and ensuring long-term stability.
- A typical use is in road construction where geotextiles are placed beneath asphalt pavements to reinforce the subgrade, preventing rutting and deformation.
- In embankment construction, geotextiles act as a separation layer between different soil types, preventing mixing and promoting uniform load distribution.
- Moreover, geotextiles can be used in drainage systems to improve the flow of water through the soil, reducing hydrostatic pressure and potential groundwater problems.

The results of performance evaluations inform the specification of appropriate geotextiles for specific infrastructure applications, ensuring optimal functionality.
Durability and Degradation of Geotextiles Under Environmental Stress
Geotextiles are engineered fabrics designed to strengthen the performance of soil in construction projects. However, their long-term performance depends on their ability to withstand the detrimental effects of environmental stress. Factors such as interaction with sunlight, moisture, and temperature variations can accelerate degradation processes, leading to a weakening in mechanical properties.
The degradation of geotextiles is a complex process influenced by both intrinsic material features and extrinsic environmental conditions. Recognizing these factors is crucial for the implementation of durable geotextile solutions that can efficiently perform their intended functions over extended times.
- Numerous studies have investigated the actions underlying geotextile degradation, focusing on biological changes at the material level.
- These investigations have discovered that factors such as UV radiation can cause photodegradation, while moisture can lead to microbial growth and hydrolysis.
- Moreover, temperature fluctuations can influence the mechanical properties of geotextiles, leading to stress over time.
To minimize degradation and prolong the service life of geotextiles, several strategies can be employed. These include:
- Utilizing UV-resistant materials and coatings
- Designing geotextiles with improved water permeability
- Implementing proper installation practices to minimize stress concentrations
By understanding the factors that contribute to geotextile degradation and implementing appropriate mitigation strategies, engineers can provide the long-term stability of geosynthetic systems.
