Evaluation of geotechnical properties of local clayey soil blended with waste materials

Abstract EN

Nowadays, disposal of waste materials has become a matter of serious concern due to environmental and ecological issues.

In this paper, an attempt is made to determine an optimum proportion mix suitable for geotechnical applications by blending the locally available clayey soil with sand, fly ash, tile waste and jute fibers.

This optimum mix provides a cheaper construction material and helps in effective utilization of waste materials like fly ash and tile waste ; thus solving the problem of disposal of waste materials to some extent.

In this research, the percentage of waste materials added to the clayey soil to make the optimum mix is obtained on the basis of compaction characteristics and the optimum mix is further checked for strength and permeability characteristics.

The basic idea behind this study is to explore the collective benefit of the material properties of waste materials when used in a composite form.

It can be revealed from this study that mixing of waste materials brings out significant improvement in geotechnical properties of locally available clayey soil.

From economic analysis, it can be concluded that the optimum mix obtained in this study yields an improved and cheaper construction material for the construction of flexible pavement.
