Abstract: Economic growth and industrialization generates huge quantities of waste materials and needs thousands of hectares of land for the disposal which creates environmental pollution. Fly ash and crusher dust come under this category. Utilization of these materials into bulk quantities in civil engineering structures can provide an alternative to natural soils and disposal problems. In this connection an attempt is made for the utilization of crusher dust and Fly ash in Geotechnical engineering applications. Tests like compaction, strength, CBR were performed on mixes prepared from crusher dust and Fly ash by varying their percentages with respect to each other. From the test results it is identified that high strength values in terms of CBR (13-15%) and angle of shearing resistance (380) were obtained by maintaining high dry densities. It is also identified that by achieving of high strength values against shear, these crusher dust- Fly ash mixes can be used as sub-grade and fill material. Therefore 30 -50% of Fly ash added to crusher dust can give better results to suit as sub-grade, fill materials in constructional activities.
