The effects of palm oil contaminant on the soaked California Bearing Ratio (CBR) of subgrade was investigated. The following objectives were set out in accordance with BS 1377: 1-8 (1990) and BS 1924 (1990); Particle Size Distribution, Atterberg Limits, Compaction and California Bearing Ratio for oil-palm contaminated and uncontaminated subgrade. Palm oil and four soil samples are used in this research work. The air-dried samples were contaminated with oil-palm at 0, 2,4, 6, 8 &amp; 10% of the dry weight of the samples for 7 days thereafter air-dried for another 7 days. Laboratory experiments on the control (0%) and palm oil-contaminated subgrade samples were conducted after 24 hours of soaking the samples in accordance with BS 1924 (1990). It was found that the soaked CBR for the contaminated soil showed a lower values (17.45%, 24.80%, 49.50% and 21.50%) than the control CBR values (48.20%, 138.40%, 160.00 and 132.10%) for sample A, B, C and D respectively. It is therefore concluded that palm oil has a negative effect on the geotechnical properties and the mechanical strength of the soil hence it is not suitable in any Civil Engineering work.
