What does soil stabilization aim to improve?

• A. Soil color and texture
• B. Strength and engineering properties
• C. Organic content of the soil
• D. Soil visibility

Answer: (B)

Soil stabilization focuses on enhancing the strength and engineering properties of soil, making it more suitable for construction and various civil engineering applications. This process typically involves modifying the physical and chemical characteristics of soil to increase its load-bearing capacity, durability, and resistance to deformation. By improving the soil's strength, engineers can reduce the risk of settling or failure in structures built on or with the soil.

This is crucial in projects such as road construction, where the soil must support heavy loads and withstand environmental stressors. Techniques for soil stabilization may include the addition of materials such as lime, cement, or polymers. By increasing the soil's engineering properties, stabilization contributes to creating more reliable and long-lasting infrastructure.

In contrast to the other options, soil stabilization does not primarily focus on changing the soil's color or texture, nor does it aim to increase organic content or enhance visibility. The primary goal is to ensure that the soil meets the necessary requirements for safe and effective engineering use.
