In road construction, non-woven Geotextilesare commonly used. These geotextiles are preferred for their filtration and separation properties. They help in stabilizing the soil, improving drainage, and preventing the mixing of different soil layers. Non-woven geotextiles are made from synthetic fibers bonded together through mechanical, thermal, or chemical processes, making them suitable for various applications in road construction, including underlays for roads, pavement overlays, and erosion control. Their durability and ability to withstand heavy loads make them ideal for enhancing the longevity and performance of road structures.
