Abstract
This paper investigates the suitability of exploiting weathered oil-contaminated soil (OCS) that resulted from the Gulf war in creating asphalt concrete used in road constructions. A full factorial experimentation methodology was adopted. The design factors considered are the oil saturation percentages and the amount of OCS relative to clean soil in concrete mix. The main response variables are the mixture stability, flow and the percentage voids in mineral aggregates (VMA) which were measured by using sieve and Marshall Tests. The analysis showed that the OCS grain size is suitable for the application. The Analysis of Variance (ANOVA) indicated that an OCS ratio of 40% to clean soil will maintain stability and flow for the wearing layer of the asphalt concrete. However, increasing the OCS percentages to up to 50% did affect the VMA of that layer. Quality control and assurance procedures for collecting samples including protections against tool cross-contamination and transport chain of custody were adopted. The results open doors towards exploiting massive amount of existing OCS in the region in road construction as opposed to the current practice of disposing it into landfills.
