In this research, waste stone sludge obtained from slab stone processing from stone washing plants
were recycled to stabilization of clayey soil with lime. Fine-powdered stone sludge was mixed with clay
soil and lime. Thus, the effectiveness of using waste stone powder and lime in stabilizing fine-grained
clayey soil (CL) was investigated in the laboratory. The soil samples in natural state and when mixed
with varying percentages of lime and waste stone powder were used to laboratory tests that included
atterberg limits tests, grain size analysis, standard proctor compaction tests, unconfined compression
tests and California bearing ratio tests. The results showed significant reduction in plasticity and changed
the optimal moisture and maximum dry density of clayey soil with increasing amount of waste stone
powder and lime. The results of the unconfined compressive strength tests and California bearing ratio
tests showed that in the different curing time, the addition of waste stone powder and lime caused an
increase in the value of UCS up to 6% waste stone powder content and 7% lime content, and increase
in the value of CBR until 6% waste stone powder content and 9% lime content, for further percentages,
the value of UCS and CBR decreased.
