Effect of Automotive Gas Oil (AGO) on Geotechnical Properties of Lateritic Soil

Akaninyene O. Akankpo, Emmanuel B. Umoren


Environmental pollution from petroleum and petrochemical products has been recognized as one of the most serious problems associated with accidental spills on a large scale. This study was carried out to investigate the effect of automotive gas oil (ago) on geotechnical properties of lateritic soil. Test carried out included Optimum Moisture Content, Maximum Dry Density, Sieve Analysis, Liquid Limits, Plastic Limits, Plasticity Index, Specific Gravity and Unconfined Compressive Test. Certain percentages of AGO (0 %, 4 %, 8 %, 12 %, 16 %) were mixed with the lateritic soil sample. Based on the results obtained, Optimum Moisture, Maximum Dry Density, specific gravity and unconfined compressive test decreased as the percentage of automotive gas oil (AGO) increased, while Atterberg limits and Sieve analysis increased as the percentage of automotive gas oil (AGO) increased. Addition of AGO to the soil led to the reduction of porosity and permeability resulting from the entrapment of the AGO within the pore spaces of the soil.
