Abstract
Building roads or platforms on weak soil is a remaining challenge. The reduction of granular material required for the subbase is more and more crucial, for cost reasons but also for a much lower impact of the earthworks on the environment. Geosynthetics have proved that they offer an effective and efficient solution. Design methods using geosynthetics have been developed for subbase stabilisation but may strongly differ depending on the model and the calibration behind. An experimental study, completed by numerical modelling has been carried out to understand better the behaviour of geosynthetic at the base of a granular layer on a weak soil.
