Effects of Contamination with Gasoline and Diesel Oil on the Value of the Oedometric Compressibility Modulus of Fine S

The following publication presents the results of a study on the effect of contamination by engine fuels, such as petrol and diesel, on the oedometric compressibility modulus of fine sand - FSa according to EN ISO 14668-1. Sand samples were contaminated with fuels at percentages of 1, 3, 5, and 10% relative to the dry mass of the soil skeleton. The results demonstrated that for the same amounts of contamination, a higher deformability was observed when diesel was the contaminant, regardless of the compressive stress range. The differences in oedometric deformation decrease with increasing impurity content in the sample. For 10% impurities, the oedometric compressibility modulus values are comparable to those of soil with a natural moisture content of 10%.
