Strength Characteristics of Copper Slag and Lime Stabilized Clayey Soil
Flexible pavement is multi-layered structure which helps in distributing traffic load over wider area of subgrade. Stability of pavement depends on strength of the subgrade soil. Non-availability of suitable material for construction of pavement is one of the major reasons which hampers the completion of the highway construction project. The disposal of waste generated in various industries like steel and copper is a major environmental and ecological issue. These waste materials can be used effectively in pavement construction because they have the potential to improve the strength of the subgrade soil. Utilization of such material to enhance strength characteristics of the subgrade soil will not only help in reducing pavement thickness but also will provide substitute for conventional material either independently or as stabilizer. Locally available soft clay was stabilized with copper slag and experimental investigations were carried out to evaluate consistency limits, compaction characteristics and strength characteristics of different combination of mixes. The strength of clay is found to increase with the addition of copper slag up to 30%. California bearing ratio (CBR) of various mixes increases with addition of lime.
