GEOTEXTILES: A MAGIC CARPET FOR WET ROADBEDS

Soft and unstable roadbeds, aggravated by heavy traffic loading, are increasingly being stabilized by using the variety of geotextiles that are now available. The evolution of these polymeric materials, woven or unwoven, and their adoption by the railroad industry are discussed. The fabrics can function to separate subgrade and ballast, to filter so that soil cannot move into the ballast, to reinforce track structures, and to aid in drainage. Methods of installation, manufacturers' activities, and possible limitations are also covered.
