Petroleum products influence the engineering behaviour of soil. Neogene clays and glacial tills from Central Poland were tested under laboratory conditions to evaluate changes selected physical mechanical parameters: particle size distribution, density, swelling, shear strength permeability. Four petroleum used in experiments: diesel fuel, kerosene, jet fuel mineral engine oil. The study revealed that even for lowest degree contamination values properties soils changed significantly. Greater variation can be expected contaminated with high-viscosity compounds. Also, higher relative found than clays. Consolidation tests soil permeability depending on composition contaminant – considerable reduction was observed light Jet while lower obtained results indicate role mesopores dimensionless pore pressure coefficient methodological issues regarding testing analysing hydrocarbon-contaminated also presented discussed, which might useful researchers studying soils.
