An assessment of the use of geogrids in unpaved roads and unpaved areas

This paper presents an assessment of the use of geogrids in unpaved roads and unpaved areas. Unpaved areas comprise working platforms, storage areas, parking lots, log yards, etc. The phrase "unpaved roads and trafficked areas", sometimes used, is not used herein because it may be confusing (as it may imply that the areas are trafficked and the roads are not, and that the areas are not unpaved). The term "stabilisation structures" will be used to encompass these two types of structures; and the term "subgrade stabilisation" will refer to this application in general. This paper includes two main parts. In the first part, a technical analysis is presented where the relevant properties of geogrids in unpaved roads and unpaved areas are discussed. In the second part, the state of practice is reviewed and factors that have an impact on the use of geogrids in unpaved roads and unpaved areas are discussed, such as: the cost of geosynthetics and aggregate, competition with geotextiles, and experience of decision-makers. The paper ends with a discussion of challenges for the future, including research needs.
