This video includes an expert explaining how lime can improve soil stabilization and help you in all types of civil engineering works and construction. What does soil stabilization do? A soils physical property is transformed to provide long-term permanent strength gains. Soil often provides the structural base for roads, building pads or parking lots are chemically treated to control engineering properties of a soil, such as moisture content.
There are three broad types of soil stabilization: biological, physical and chemical. The expert says that in this process of soil stabilization, they add lime in order to break down the clay. This is because the clay particles absorb sodium, and sodium absorbs water. By getting rid of the clay, it can help prevent the soil from retaining moisture that can otherwise disrupt the construction process. Then they come and mix the existing clay soil in with the lime. The soil gains much more density and strength. You can see the structural change in the integrity of the soil in real time.
After a waiting period, the new soil is ready for continued instruction and laying down pavement or cement. This process helps ensure a stable starting point for roads and parking lots.
