Part 1: Functions and applications of geosynthetics in roadways

February 1, 2017

Introduction The geosynthetic products most commonly used in roadway systems include geotextiles (woven and nonwoven) and geogrids (biaxial and multiaxial), although erosion-control products, geocells, geonets (or geocomposite drainage products), and geomembranes have also been incorporated in a number of projects. These various types of geosynthetics can be used to fulfill one or more specific functions …
