The physical and mechanical properties of soils change when soils are contaminated by oil products. This study investigates the effect of diesel oil contamination on the geotechnical properties of granitic residual soil. To better understand the behavior of oil-contaminated granitic residual soils, an experimental laboratory investigation was performed on granitic residual soil that was polluted by different amounts of diesel (0 to 15% by soil dry weight). In this paper, the geotechnical properties of clean and contaminated samples, including compaction characteristics, Atterberg limits, shear strength parameters, disintegration rate, and permeability coefficient, were evaluated through tests. The test results indicate that diesel oil has adverse effects on all aspects of the geotechnical properties of granitic residual soil. With the increase in oil content, shear strength parameters, compaction characteristics, and Atterberg limits appear to have different degrees of decline, and granitic residual soil is more likely to disintegrate.
