ABSTRACT
Reinforced soil, or mechanically stabilized soil, is a construction material that consists of soil that has been strengthened by tensile elements such as metal strips, geotextiles, or geogrids. In the 1960s, the French Road Research Laboratory conducted extensive research to evaluate the beneficial effects of using reinforced soil as a construction material. Results of the early work were well documented by Vidal.1 During the last 40 years, many retaining walls and embankments were constructed all over the world using reinforced soil and they have performed very well.
