ENHANCING THE PROPERTIES OF SOIL BY STABLIZATION TECHNIQUE USING BASALT FIBER

Abstract

Soil stabilization is the process of the alteration of the geotechnical properties to satisfy the engineering requirements. Numerous kinds of stabilizers were used as soil additives to improve its engineering properties. A number of stabilizers, such as lime, cement and fly ash, depend on their chemical reactions with the soil elements in the presence of water. Other additives, such as basalt fiber, plastic waste, wood chippers, rubber tyres pieces, sugarcane rusk ash, plant roots, depend on their physical effects to improve soil properties. In addition, it can be combined both of chemical and physical stabilization. In recent times, with the increase in the demand for infrastructure, raw materials and fuel, soil stabilization has started to take a new shape. With the availability of better research, materials and equipment, it is emerging as a popular and cost-effective method for soil improvement. This study provides details of advantages and disadvantages of using basalt fiber as soil stabilizer. The organic soils are unsuitable for construction works due to its low shear strength, high swelling potential and poor bearing capacity. These types of soils can be treated by stabilization and compaction methods. In this research, study on effective use of stabilization using basalt fiber in varying proportions and the main objective of this study is to increase the geotechnical properties of soil.
