Part 1: Functions and applications of geosynthetics in roadways

February 1, 2017  |  Features

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 num…

Part 3: Field evaluation of the performance of unpaved roads incorporating geosynthetics—Implementation

June 1, 2016  |  Features

Introduction The mechanisms that govern unpaved road performance are complex, and accurate field evaluation of the performance of unpaved roads incorporating geosynthetics is not easy because it involves many influence factors. Interpretation of test data can be correct only if there is a good under…
