Due to the globalization of the world economy existing ports are being developed and new ports are being built in order to cope with the increasing volume of goods in transit. New container terminals or port extensions are mostly built on reclaimed land from the sea. As the nourishments with their low or medium density of the fill provide insufficient bearing capacity to take up the final loads of the container terminals, the long-term stability and trafficability of the gained land must be improved. An economic measure to improve the bearing capacity of existing and newly developed terminal areas is the use of geogrid/nonwoven composite material as reinforcement and separation layers. As the geogrid can absorb greater tensile stresses than the base course itself, the tension in the reinforced base course is reduced. This leads to a more efficient load distribution within the base course and thus to less vertical deformation (settlement and rutting) at the pavement surface, which thus significantly increases the serviceability of these intensively used traffic areas. This paper will give an overview on the state-of-the-art using geogrid/nonwoven composite materials to increase the bearing capacity of the base course at various international port projects as e.g. in Turkey and the Sultanate of Oman.
