Soil Stabilization Soil Modification - PPRA

Chemical additives such as lime, fly ash, and cement can be added to these soils to dry and improve the workability of the soil. Soil modification refers to the process of adding and mixing the above chemical agents into the soil to not only dry the soil, improving workability, but also reducing the plasticity index (PI) and shrink swell potential.
