Comprising over 70% of earth's surface, water and its adjacent areas is undoubtedly the most precious natural resources that exist on our planet. Areas surrounded by the coast have been highly utilized since ancient times. Several National and International authorities have mandated to develop coastal structures as part of infrastructure development. The various potential problems associated with these Marine soils include land slippage, slope instability, poor foundation support and poor drainage. Problems often arise when roads or other structures are to be constructed on soft ground. In the case of soft marine clay deposits the bearing capacity is often found be too small and even if the subsoil can sustain the loads, resulting settlements may betoo large. In the case of Flexible Pavements, unless the subgrade is appropriately treated at the construction stage, the transportation cost will increase substantially due to deteriorated pavement performance. There are many methods of stabilization of subgrade marine clay. Treating the soil with lime, cement and lime-cement combinations is a unique technique to improve the engineering properties of the marine clay. The main objective of this work is to study the effectiveness of additives at different percentages on the engineering properties of marine clay.
