STABLISATION OF SOIL WITH MARBLE WASTE ON HIGHWAY SHOULDERS

Large volumes of earthen materials are used in construction each year in India and elsewhere. The wastes generated from these materials can be utilized in various applications including highway shoulders. In this study, three different types of wastes namely local soil of Jaipur city and marble dust are used. These wastes were mixed with natural soils as a potential alternative filling materials in the highway shoulders. Two types of natural soils were mixed with 0%, 5%, 10%, 15%, and 20 % of, marble dust. Standard compaction, permeability and saturated California Bearing Ratio (CBR) tests, and analysis were performed on two types of natural soils, containing three industrial waste types in different ratios. The study indicates that the marble dust and waste sand are fairly good additive materials in highway shoulders fill and reaction substantially improves their CBR, swelling ratio and water conductivity. It was found that a clear optimum replacement level of 15 % for all of these by products for medium and low plasticity type of soil
