SOIL STABILIZATION USING WASTE PLASTIC MATERIAL

Abstract

The Ultimate deciding factor for design of a highway pavement is Sub grade Strength. The sub grade
strength is a function of Gradation and Soil Characteristic, which is measured in terms of CBR. It is uneconomical
and difficult to design Pavements for high CBR in locations where the Soil has low CBR. Thus to optimize the
Pavement and Design and Cost the existing CBR of the Soil needs to be improved by Stabilizing the existing
Soil. The present Study aims to evaluate the effect caused by the different Stabilizing Agents on the geotechnical
characteristics of expansive/Low CBR sub grade soils. The soil will be treated with varying percentages of
Stabilizing Agents 0, 5, 10, 15, and 20 and the improvement/Change in Consistency limits, compaction,
California Bearing Ratio, swell potential will be studied for treated and untreated soils. The aim of the study is to
identify the Optimum Stabilizing Content for Desired Strength and Cost.
