Geotechnical behavior of a tropical residual soil contaminated with gasoline

Abstract

The infrastructure for hydrocarbon transportation has grown significantly to supply the needs of a greater number of settlements; however, due to problems in the supply networks, accidental spills or leaks can contaminate the underlying soils. This paper addresses soils contaminated with gasoline, and it analyzes the changes that occur in a tropical residual soil after contamination. Analysis was carried out by using specific laboratory tests to characterize the type of soil (Miniature Compacted Tropical Classification, Suction, Pinhole Test, Collapse Potential, X-ray Diffraction, Scanning Electron Microscopy, pH determination) and by performing traditional tests (natural humidity, specific gravity, granulometry, Atterberg limits, direct shear, etc.). These tests were conducted with samples in their natural state, as well as contaminated samples, in order to elucidate possible variations in the mechanical characteristics of the material.

Effects of hydrocarbon contamination on the engineering geological properties of Neogene clays and Pleistocene glacial tills from Central Poland

“…Processes taking place in the microstructure of contaminated soils are reflected in the macroscopic characteristics of the particle size distribution. Because of flocculation caused by contamination with oil-derived products, an increase of silt-size aggregates is observed, and thus there is a diminishing contribution of the clay fraction (Korzeniowska-Rejmer 2001;Izdebska-Mucha 2005;Gupta et al 2009;Echeverri-Ramirez et al 2015;Stajszczak 2019).…”
