Fine-powdered stone sludge was mixed with claysoil and lime. Thus, the effectiveness of using waste stone powder and lime in stabilizing fine-grainedclayey soil (CL) was investigated in the laboratory. The soil samples in natural state and when mixedwith varying percentages of lime and waste stone powder were used to laboratory tests that includedatterberg limits tests, grain size analysis, standard proctor compaction tests, unconfined compressiontests and California bearing ratio tests. The results showed significant reduction in plasticity and changedthe optimal moisture and maximum dry density of clayey soil with increasing amount of waste stonepowder and lime. The results of the unconfined compressive strength tests and California bearing ratiotests showed that in the different curing time, the addition of waste stone powder and lime caused anincrease in the value of UCS up to 6% waste stone powder content and 7% lime content, and increasein the value of CBR until 6% waste stone powder content and 9% lime content, for further percentages,the value of UCS and CBR decreased.
