Sand dunes are formed due to the earth’s erosional and depositional forces. Dune sand being collapsible and due to lose formation, is not suitable to be used as subgrade material for pavements or any other infrastructure applications as its sand grains contain large voids in between which results in its poor gradation and inability of being compacted. The prime objective of this research paper is to estimate the feasibility of using and converting dune sand into sustainable fill material and improving its engineering characteristics as well as its gradation using pozzolanic cement supplementary wastes in optimum proportion. To achieve this objective three types of pozzolanic wastes viz. Wheat straw ash (WSA), Fluid catalytic cracking catalyst residue (FC3R), Nano silica (NS) were used replacing cement partially in proportion of 2%, 3%, 4% and 5% respectively aggregating total additives (waste + cement) as 8%, 10%, 12% and 14%. The engineering parameters MDD, OMC, UCS and CBR are mainly evaluated from this study. From the results and analysis, it is observed that partial replacement of 2% WSA, 14%FC3R and 3%NS showed the maximum improvement in UCS values. Further the results obtained for various percentage of dosages were compared with recommendations given by IRC for cement stabilization.
