Due to the globalization of the world economy and the global increase of trade, there is an increasing shipment of goods which creates high demands on the maintenance and development of an efficient infrastructure (roads & railways). The development of infrastructural projects will be a booming sector of the construction industry. Limited budgets of the contracting authorities are current boundary conditions which can be accommodated optimally with geosynthetic solutions as an alternative to conventional construction methods. Besides the technical advantages, the economical and ecological advantages can be used to reduce construction costs and to take care of building materials resources. The paper will present international projects in the field of railway rehabilitation, road construction and slope reinforcement.
