Geogrids - what is important

Geogrids are frequently used for stabilisation and reinforcement of the unbound courses in transportation engineering. Benefits of their use are well known, but many times poorly understood in terms of mechanisms that govern their performance. Their performance is based on interaction with granular soil surrounding it. Paper deals with the importance of geogrid structure, geometry, junctions and mechanical properties of geogrid in relation to granular material in which they are intended to be installed. Some basic important facts on interaction between geogrid and soil are presented through experimental results and some theoretical aspects of mechanical behaviour are discussed. Current and future trends of research in this filed are highlighted.
