ABSTRACT
On request of Finnish Transport Infrastructure Agency (Finland), Norwegian Public Roads Administration (Norway) and Swedish Transport Administration (Sweden), Sintef (Norway) has prepared guidelines on the use of geosynthetics in Nordic conditions. The ROUGH project (RecOmmendations for the Use of GeosyntHetics in Nordic conditions) has been realised together with several manufacturers of geosynthetics. The paper focuses on the behaviour of drainage geosynthetics during installation in Nordic conditions. The test conditions included prior storage at Nordic temperatures under which the products were also installed, Nordic conditions such as crushed rock and compaction, followed by laboratory tests of the exposed and unexposed geosynthetic samples.
