Lime and Cement Treatments of Subgrades in Southern Italy: Facing Interports Issues and Challenges

Abstract The objectives of this paper are confined to the assessment of the best stabilization techniques to improve soils, thereby optimizing pavement performance and sustainability for a given type of soil. In order to pursue these objectives, an experimental plan was conceived and implemented. The results led to several conclusions pertaining to lime stabilization potential for improving the performance of weak soils, proportionality between ITS and UCS properties, and potential of combined treatments as a strategy for improving the immediate achievement of the target performance in a short duration. Outcomes of this study are expected to benefit both practitioners and researchers.
