Abstract


The current study involves the improvement of laterite soil by addition of granite dust. The laterite and dust used for the study were collected at Elerinjare town, Ilorin. The analyses were done in a laboratory. The tests are compaction test, specific gravity, California bearing ratio (CBR) (soaked and unsoaked), Atterberg's limit, Sieve analysis, and bulk density. In this investigation, an attempt was made to stabilize lateritic soil using quarry dust for improving the sub-base and subgrade strength, the properties of the soil show that the specific gravity of lateritic ranged from 2.1 to 2.5, and that of granite dust ranged from 2.50 to 2.68. Various percentages of rock dust (10%, 25%, and 50% of soil samples) were added to the soil, and the soil with 50% granite dust gave the best results. All the tests show that the samples are suitable for pavement, that is, road construction.
