EVALUATION OF STRENGTH CHARACTERISTICS OF CLAYEY SOIL USING BASALT FIBER AND GROUND GRANULATED BLAST FURNACE SLAG

Abstract

The fundamental requirement of humanity is met by transportation. Everyone has traveled for food or pleasure since the beginning of time. Because there is a direct link between the caliber of a nation's transportation infrastructure and its level of development, everyone has high expectations for these facilities. Today's civil engineers have significant hurdles in creating transportation systems that are analytically sound, economically sound, environmentally benign, socially believable, sustainable, and practicable. The inadequacy of traditional construction techniques in the contemporary environment is generating interest in technologies like ground improvement. The development of the economies of developing nations like India depends heavily on the availability of an affordable road network. When it comes to highways, a weak subgrade layer of the pavement necessitates a thicker pavement, which raises the cost of building the pavement. Because of their weak shear strength, high potential for swelling, and poor bearing capacity, organic soils are not appropriate for construction work. Methods for stabilization and compaction can be used to address these sorts of soils. The major goal of the study in this work is to improve the geotechnical qualities of soil by the effective usage of stabilization utilizing basalt fiber and ground granulated blast furnace slag (GGBS) in varied quantities. The study used 2%, 3%, and 4% of basalt fiber and 5%, 10%, and 15% of powdered granulated blast furnace slag in three different amounts. Compaction and an unconfined compressive test (UCS) were performed on the reinforced soil. The findings of the trial indicated that the soil's compressive strength and shear strength had been effectively improved. Key Words: Compaction test, CBR, UCS, Basalt Fiber, GGBS
