Geotechnical Evaluation of Diesel Contaminated Clayey Soil

Soil contamination by different hydrocarbons has rapidly expanded worldwide, surpassing the self-purification capacity of soils and increasing number contaminated sites. Although much effort been devoted to study effects diesel on geotechnical properties soil, there is still limited available information about it. Moreover, no maximum retention that soil can have its effect behavior soil. Thus, in this paper, we determined an unsaturated clayey evaluated impact properties. The results showed could only retain 12.6% added excess was expulsed. At such a concentration, saturation rate lower than 80%. Diesel increased plasticity internal friction angle while cohesion considerably decreased. It should be noted matric suction one obtained for natural However, osmotic higher. This indicates must considered evaluate shear strength soils.
