Soil Stabilisation Techniques for Problematic Soils: A Review

  • Bimalendu Dash, Indra Kumar Karri, Sai Santosh Basina

Abstract

Treating weak soils with various additives is not a new technique; it was started in the 1960s with the oldest known stabilizer called "cement". Even before that, in the 1920s, an attempt was made in improving the roads. By product of paper mills, were mixed with clayey soils to get strengthened surface, but it hasn't got much attention in those days. This paper reviews on stabilizers that are highly used in improving the strength properties of problematic soils. Different eco-friendly materials like RHA, coconut shell ash, and industrial wastes like Flyash, EAFD etc., when mixed individually with soil, showed reliable results. The variation of properties of composite soil (i.e., mixed with stabilizers) like UCS, CBR, Atterberg limits etc., are depicted graphically, and their optimum contents are determined. Also, Nanomaterials like Nano silica, Nano clay and others are studied when mixed with soil at different proportions. Also, other materials like biopolymers, CCR, Geosynthetics etc., are included in stabilizing soil, and their composition, benefits, advantages are mentioned.
