This paper presents the types, functions and technologies using geo-synthetic material with an analysis of their use in the construction,rehabilitation, reconstruction, substitution, repair and maintenance of forest roads. Geo-synthetics are all building materials in the form of synthetic origin polymers (polypropylene, polyethylene, polyvinyl chloride, polyester) that are used in a variety of geotechnical structures in the construction industry in general, and in the forest construction. Although there is great potential for their application, these materials have not been used in engineering of forest roads in Serbia.
