Lime Stabilization

Lime Stabilization

Lime stabilization is a ground improvement technique that involves adding lime to the soil to improve its properties. Stabilization is achieved when the proper amount of lime is added to a reactive soil and exchange of ions occurs. Clayey soils of moderate to high plasticity are suitable for implementing this technique. Sufficient curing time has to be provided, as the rate of strength gain is rapid during initial stages. The gain in strength is also affected by the temperature at which curing takes place. High temperature during curing leads to enhanced strength. Lime stabilization technique is usually used in road construction to improve sub-bases and subgrades and for railroad and airport construction.
