The Invisible Foundation: How Geotextile Fabric is Transforming Road Construction
Modern infrastructure especially road and highway construction is always facing problems arising from unstable subgrades, poor drainage and, as a result, wear and tear due to the traffic load and weathering. A large part of this problem has been solved by the use of an expensive and thick layer of granular aggregate for around half a century. A completely different approach to the problem has been introduced by the arrival of the new polymer-based textiles. Geotextile fabric is the most important and, at the same time, the invisible, the foundation of the road, which is either paved or unpaved and, moreover, it is a permeable material most often made of polypropylene or polyester. Increased road and highway construction sustainability in terms of materials, finances, and time to understand how to use this material and its functionality is very important. Geotextile fabric can be considered a very versatile material that can work as a road construction base and perform the primary four ...
