The scarcity of soil which suits for construction activities by fulfilling geotechnical characteristics is forcing the pavement engineers to look for alternative materials for construction activity. On the other hand due to the rapid industrialization there is sharp increase in the number of crushing units, steel producing factories in so many states and the country as well. The crusher dust and Blast furnace slag obtained from these industries are collected and tested for various geotechnical characterizations. The suitability of partial or full replacement is checked by conducting CBR tests on various mix portions. In the present investigation, crushed stone as coarse aggregate mixed with Crusher Dust, Blast Furnace Slag and Sand as fine aggregate and tested for compaction OMC and MDD and strength CBR characteristics to suit as base course material along with their relative performance. It is also studied partial replacement of Crusher Dust, Sand by Slag particles 50 with respect to their gradation mixes. From all the studies it is identified that average gradation obtained higher VBR values than lower and upper gradation for all types of fine aggregates due to their dense or compactness by possessing effective well graded conditions. Lower gradations obtained CBR values nearing to their average gradation which are higher than upper gradation mixes. The same trends are also observed in case of 50 replacement. Hence replacement of natural soil like gravel, sand by crusher dust and slag particles with their maximum utilization such as partial or full replacement with crushed stone particles attaining CBR values greater than 80 can be used in road construction as base-course material.
