Abstract

The present study aims to explore the possibility of reclaiming petroleum oil-contaminated soil for its use as a pavement subbase material after the stabilization/solidification treatment. The contaminated soil was characterized in terms of its geotechnical and chemical parameters using samples collected from a beach site that was contaminated by petroleum oil spillage. Two industrial solid wastes: cement kiln dust and limestone powder along with ordinary Portland cement were used as alternative stabilizers. The performance of the selected stabilization/solidification treatment strategies was evaluated using the results of mechanical and chemical tests carried out on the specimens of soil after the treatment. Based on the evaluation of test results, it was found that a combination of cement kiln dust and Portland cement (30% and 1.46%) and (30% and 4.12%) can be optimally used as stabilizer for stabilization/solidification treatment of the contaminated soil to deliver a subbase material for rigid and flexible pavements, respectively. The toxicity characteristics leaching procedure analysis revealed that the heavy metals concentrations in all sets of the treated soils were significantly lowered and were found to be within the USEPA permissible limits.
