In this workshop, the current design practice and the recent developments for the use of geogrids
in stabilization and base reinforcement applications will be reviewed. Both empirical and M-E
design approaches will be presented. The development of a design method within the framework
of the mechanistic-empirical design method will address. The implications of these design
approaches in relation to long-term pavement performance will be discussed. The life cycle cost
benefit for each of these applications will be examined.
Geogrids are made from synthetic polymers, and of these, polypropylene, polyester, and
polyethylene are by far the most common. These polymers are normally highly resistant to
biological and chemical degradation. Less-frequently-used polymers include fiber glass for
the grid structure. Polyvinyl chloride (PVC) is also used for coating some geogrids. Natural
fibers such as cotton, jute, etc., could also be used to make materials that are similar to
geogrids. Because these products are biodegradable, they are only for temporary
applications. Natural fiber geogrid type materials have not been widely utilized in the U.S. ,EU ,China etc Areas
