SOILS-BALLAST-GEOTEXTILE RELATIONSHIP: PART 1--BALLAST AND SUBGRADE

Geotextiles, engineering fabrics, can be properly used only if there is an understanding of the surroundings in which the material is to be placed. This first installment presents information on the soils and ballast environment in which geotextiles are applied, defining common soils and stress conditions that require frequent addition or replacement of ballast to retain track geometry. Also examined are the resilient responses and permanent deformation within the subgrade and ballast. The subsequent article lists the contributions and limitations of fabrics in track-structure applications.
