Stabilisation with geogrids for transport applications – selected issues

Stabilisation is defined as improvement of the mechanical properties of an unbound granular material by including one or more geosynthetic layers such that the deformation under applied loads is reduced by minimizing soil particle movement. Paper discuss geogrids as type of geosynthetics which when used in stabilisation function for transport applications could provide real improvement in performance of aggregate layer. Such function has been called for a quite long time as the reinforcement of subbase, base or ballast, depending on the applicatio
