Yes, geotextiles can be used in road shoulder reinforcement. Geotextiles are commonly used to stabilize and reinforce the soil by acting as a separator, filter, and reinforcement material. They can prevent the migration of fine particles, improve soil drainage, and enhance the overall stability of road shoulders.

There are several factors that can affect the permeability of geotextiles. These include the type and thickness of the geotextile material, the size and shape of the pores within the material, the level of compaction or density of the material, the presence of any clogging agents such as fine particles or organic matter, and the pressure gradient or hydraulic gradient across the geotextile. Additionally, environmental factors such as temperature and moisture content can also influence the permeability of geotextiles.

When selecting geotextiles for mine tailings management, several considerations should be taken into account. Firstly, the geotextile should have adequate permeability to allow for proper drainage and prevent the accumulation of water within the tailings. It should also possess sufficient strength and durability to withstand the harsh conditions present in mining environments, including chemical exposure and abrasion. Additionally, the geotextile should have good filtration properties to prevent the migration of fine particles from the tailings and the loss of valuable materials. It should also be resistant to clogging and provide long-term stability to ensure the integrity of the tailings storage facility. Furthermore, the geotextile's compatibility with the tailings material and the surrounding environment is crucial. It should be chemically inert to avoid any adverse reactions with the tailings or surrounding soils. Environmental factors such as temperature, pH, and exposure to sunlight should also be considered. Lastly, the cost-effectiveness of the geotextile should be evaluated. This includes considering the initial installation cost, as well as the potential for maintenance or replacement in the future. Ultimately, the selection of a suitable geotextile for mine tailings management should prioritize functionality, durability, environmental compatibility, and cost-effectiveness.
