Abstract: The use of geosynthetics in construction has increased dramatically in the last decade. Geogrids are one of the geosynthetics that have seen increased use in railroad applications. In conjunction with design of railroad track at several military installations the question was raised as to the benefit of including a geogrid in the ballast to act as a reinforcement mechanism. The use of geogrids in railroad track applications was investigated to determine if the ballast thickness can be reduced using geogrids. Included in the study was the investigation of the advantages and disadvantages of using geogrids along with the possibility of reducing the ballast thickness through the use of a geogrid. All available technical literature applicable to the use of geogrids in railroad track was reviewed during this study. In addition, a number of telephone calls and personal contacts were made with people in academia and in the geosynthetics and railroad industries who have been involved with the development, testing, and use of these materials in railroad track. A synopsis of the information that is currently available in relation to the use of geogrids in railroad track reinforcement is presented along with recommendations for the use of geogrids on low traffic density, low speed railroad tracks typical of those found on military installations.
