Chemical stabilization on the other hand is a method that involves adding chemicals into the soil. The major reasons for performing soil stabilization include: Improvement of strength, bearing capacity as well as other engineering properties of soils. determining and developing soil stabilization practices on Caltrans owned roadways. However, bitumen is not environmentally friendly and becomes brittle when it dries out. There are several types of additives used for chemical stabilization, but the choice of additive is based on the type of soil. changing composition of soil by adding or removing different soil particles. If you are working the road construction industry, one of the key things that you need to consider is the quality of the equipment. A strength gain of 100 psi (700 kPa) for a soil-cement mixture over the natural soil shall be considered adequate for cement stabilization with 4% cement by dry weight of the soils and tested as described above Soil stabilization is used to reduce permeability and compressibility of the soil mass in earth structures and to increase its shear strength. SOIL STABILIZATION BY VARIOUS ADDITIVES/AGENTS Stabilization of soils to improve strength and durability properties often relies on cement, lime, fly ash, and asphalt emulsion. The term soil stabilization means the improvement of the stability or bearing power of the soil by use of controlled compaction, proportioning and the addition of suitable admixture or stabilizers. Lime has been used as a soil stabilizer for roads from olden days.
