Crushed waste concrete (CWC) has been added to soil subgrades with inadequate natural stability to evaluate how it affects their behavior. The soils were mixed with various percentages of crushed waste concrete 0 %, 25 %, and 50 %, which were selected based on previous studies. Natural clay soil (Neat Soil)-crushed waste concrete CWC mixes were compacted at the optimum water content and then subjected to a variety of laboratory tests. The results revealed that soil samples stabilized with CWC improved significantly in terms of swelling pressure, maximum dry density, and California Bearing Ratio (CBR). The swelling pressure decreased by increasing CWC contents for all samples and the maximum dry density value, CBR value of Blend Soil (X1, X2) samples increased with increasing CWC contents. Therefore, the CWC is a valuable material for modifying the properties of soil in order to make it appropriate for construction. Based on the results analysis, mix designs containing 50 % CWC and 50% silty clay soils were found to be appropriate for use as sub-base material.
