When clayey soil is treated with lime, Cation exchange between them increases plastic limit and reduces plasticity index, which finally results in an increase in soil stability. Lime-Soil stabilized mix is useful to construct sub-base and base course for pavement.

Lime stabilization is a soil improvement technique that involves adding lime to the soil to increase its strength, durability, and load-bearing capacity. It is a widely used technique in civil engineering and construction projects to improve the properties of soils that are unsuitable for construction.

The correct answer to the question is option 'D', which states that lime stabilization is very effective in plastic-clayey soils. This is because clayey soils have a high percentage of fine particles, which makes them highly susceptible to shrinkage and swelling due to changes in moisture content. These soils also have low bearing capacity and are prone to cracking and erosion. Lime stabilization helps to modify these properties of the soil and make it more suitable for construction.

How Lime Stabilization Works:

Lime stabilization works by introducing lime into the soil, which reacts with the clay particles and causes them to flocculate or clump together. This process reduces the plasticity of the soil by increasing its shear strength, stiffness, and permeability. The lime also neutralizes the acidity of the soil, which prevents the formation of harmful compounds that can damage structures built on the soil.

Benefits of Lime Stabilization:

- Increases the load-bearing capacity of the soil: Lime stabilization increases the strength and stiffness of the soil, making it able to support heavy loads without deformation or failure.
- Improves the durability of the soil: Lime stabilization reduces the susceptibility of the soil to erosion, cracking, and other forms of damage, making it more durable and long-lasting.
- Reduces the plasticity of the soil: Lime stabilization reduces the plasticity and swelling of clayey soils, making them more stable and less prone to deformation.
- Improves the workability of the soil: Lime stabilization improves the workability of the soil, making it easier to compact and shape into the desired form.
- Reduces the cost of construction: Lime stabilization can significantly reduce the cost of construction by eliminating the need for expensive excavation, backfilling, and replacement of unsuitable soil.

Conclusion:

In conclusion, lime stabilization is a highly effective soil improvement technique for plastic-clayey soils. It helps to modify the properties of the soil and make it more suitable for construction, reducing the cost and time required for construction projects.
