Efficient traffic routes form the basis for a brisk economic trade and a close economic and social relationship of different countries. Thus, the massive development of the national and international traffic routes is correspondingly important. Especially in densely populated areas the routes have to be designed and constructed in such a way that emissions remain compatible for the direct surroundings. In this case the modern construction management requires solutions which are well-engineered and which can be carried out economically friendly while the visible parts of the constructions should suit to the landscape in an ideal way. Thus, geosynthetics are used for the static design of high dams and noise protection barriers, in case of a foundation on extremely weak subsoil and for ground water protection measures. Large-scale projects actually realized as well as constructions monitored since years stand representatively for the possibilities and the importance which geosynthetics provide for the use in important infrastructural projects. The first part of this paper gives information about the current guidelines for the design of geosynthetics reinforced structures in Europe. Part two of the paper provides interesting case studies of infrastructure projects worldwide which have been realized with geogrid reinforced retaining structures.
