Abstract

Crude oil spills have become regular in some communities where oil exploration activities are being carried out. This has impacted negatively on the environment, such as soil contamination. The aim of this experimental investigation is to contaminate a lateritic clay soil with crude oil and determine the effects of such contamination on the plasticity, strength and permeability of the soil. The soil was contaminated by adding varying percentages of crude oil to the soil. Specific gravity, Atterberg limits, compaction, California bearing ratio (CBR) and permeability tests were conducted on the uncontaminated and contaminated soil samples. The liquid limit, plastic limit and plasticity index of the soil increased as its crude oil content increased. The specific gravity, optimum moisture content, maximum dry unit weight, CBR and permeability of the soil decreased as its crude oil content increased. The crude oil contaminated soil requires stabilization or remediation before using it as a construction material.
