A STUDY ON STABILIZATION OF SOIL WITH LIME AND CEMENT

Abstract

This paper presents the study on the use of Lime and Cement for stabilization of soil. Poor sub-grade soil is problematic due to its settlement, swelling and strength issues. High strength soil in subgrade is recommended by IRC: 37-2012, the code for the design of flexible pavement, which recommends the use of select soil of minimum CBR 8% in the sub-grade when the traffic is 450 Commercial Vehicle per day or higher. This study aims to improve the engineering properties of sub grade soil by stabilization of soil with lime and cement. The stabilization of soil with lime and cement is an easy approach. In the present study experimental investigations have been conducted on locally available soil by mixing it with cement and lime in proportions of 1%, 2%, 3% and 2%, 4%, 6% respectively. The
effects of stabilization on Maximum Dry Density (MDD), Optimum Moisture Content (OMC) and California Bearing Ratio (CBR) of composite mixture have been assessed. The whole experimental study has been done in two steps. In first step, a series of experiments such as Atterberg Limits, Modified Proctor test and California Bearing Ratio tests have been conducted on untreated soil and in second step Modified Proctor tests and California Bearing Ratio tests have been performed on composite mixtures of soil plus lime and cement. It has been found that mixing of lime and cement with untreated soil proved to be effective in enhancing engineering properties of the subgrade soil.
