In our highways, stabilization applications carried out with geosynthetics and evaulated effectiveness and theoratical operating mechanisms of geosynthetics comparatively

Geosynthetics which have been produced in a factory controlled characteristics, have advantages such as space savings, material quality control, construction quality control, cost savings technical superiority, consruction timing, material development, material availability and environmental sensitivity for the solution of encountered geotechnical problems in transportation projects. In the first chapter of the thesis, a general view of geosynthetics has given dealing with this product's definitions, functions and usage areas comparatively and the soil stabilization methods using TENAX (that is an international company at syntetic products) geosynthetics has been explained. In the last chapters, applications carried out using with geosynthetics materials in our country's highways have been analysed comparing with conventional soil stabilization methods. Finally in the world, some different applications made with geosynthetics has been presented as case history.
