Lime stabilisation of fine grained soils is a well tested technique, traditionally used to improve clay subgrades for road pavements. Recent applications in stabilisation have emerged, producing alternative solutions to geotechnical problems, such asthe reuse of unsuitable materials in earthworks. In the paper the effects of the addition of lime on soil structure are investigated. Results from laboratory tests on a natural silty soil are reported. The natural and lime stabilised samples were dynamically compacted at different initial water content, and dried by means of a pressure plate apparatus in order to point out the modification induced by lime on the water retention properties of the soil.
