However, increasing hydrocarbon pollution arising from fuel<br>stations, automobile workshops, and industrial activities has raised concerns regarding the suitability of<br>contaminated lateritic soils for construction purposes. This study investigates the effect of diesel oil<br>contamination on the geotechnical properties of laterite soil obtained from Federal Polytechnic Nekede, Nigeria.<br>Laboratory tests were conducted on uncontaminated soil and samples contaminated with varying diesel contents<br>of 2%, 4%, 6%, and 8% by dry weight. The tests included particle size distribution, Atterberg limits, Standard<br>Proctor compaction, and California Bearing Ratio (CBR). Results show that diesel contamination causes a<br>progressive reduction in maximum dry density and CBR, accompanied by noticeable changes in consistency<br>limits and compaction behavior. The CBR value decreased from 49.36% for the natural soil to about 21.23% at<br>higher diesel contents, indicating severe loss of bearing capacity.</p> |
