What are the key factors to consider when selecting the appropriate geotextile for a road construction project?

When selecting the appropriate geotextile for a road construction project, several key factors should be considered. These factors include:
1.Function and Application: Determine the specific purpose of the geotextile in the road construction project. Whether it’s separation, filtration, reinforcement, or erosion control, understanding the intended function will help in selecting the right type of geotextile.
2.Strength and Mechanical Properties: Consider the required strength and mechanical properties of the geotextile to withstand the expected loads and stresses. Key properties to evaluate include tensile strength, puncture resistance, and elongation characteristics.
3.Permeability: Assess the required permeability of the geotextile based on the project’s drainage needs. The geotextile should allow for proper water flow while preventing the migration of fine particles that could clog the drainage system.
4.Soil Compatibility: Evaluate the compatibility of the geotextile with the soil conditions at the project site. Consider factors such as soil type, pH levels, and potential chemical interactions to ensure the geotextile’s long-term performance and durability.
5.Durability: Determine the expected lifespan of the road and select a geotextile that offers sufficient durability to withstand environmental factors, such as UV exposure, temperature fluctuations, and chemical exposure.
