Making the use of locally available byproducts to encourage the proper management of economy and environment has now become an essential objective of an engineer. Treatment of soil with various materials to upgrade the soil properties and make if suitable prior any kind of construction is significant as working without testing and treating the soil conditions may lead to failures in all the sectors of work. The intention and motivation of this study and research is to make use of waste marble dust and sisal fibers to enhance the soil quality sub-grade soil for the construction of road. Waster marble powder is taken in various content likewise sisal fibers of 10mm average length is taken and mixed together with the soil sample. Compaction test, CBR, consistency test is the basic tests performed in this study to verify the effect of additives of marble dust and sisal fiber on the soil. This study is motivated towards the study of effect of marble dust and sisal fibers when mixed in various content with the clayey soil.
