What is the main purpose of soil stabilization?

The main purpose of soil stabilization is to improve load-bearing capacity. This process involves enhancing the physical properties of soil to increase its strength and durability, which is essential for construction purposes. When soil is stabilized, it can support heavier loads without failing, making it suitable for building roads, foundations, and other structures where stability and strength are critical.

Soil stabilization techniques, such as the use of chemical additives or mechanical methods, can significantly alter the soil's characteristics to better handle the pressure and weight imposed on it. For example, stabilizing clayey soils can reduce their plasticity and swell potential, resulting in a more stable foundation for structures.

Other options, such as increasing water retention or enhancing soil aesthetics, may be beneficial but are not the primary focus of soil stabilization. While reducing soil acidity is important for agricultural purposes, it does not directly relate to the overarching goal of ensuring soil can adequately support structures and loads.
