dc.abstract.enThe effect of contamination with petroleum substances (A1 jet fuel and 15W40 mineral oil) on the compressibility and consolidation of mixtures of ice-dammed clay and aeolian sand was determined in a Barden–Rowe consolidometer adapted for liquid-phase contamination tests. The deterioration of the filtration capacity of the contaminated soil medium relative to the non-contamination condition is reflected by the mobilization of higher values of pore pressure u b and pore water pressure parameter C CL in the course of consolidometer tests. As a consequence, lower values of the compressibility modulus M 0 and the consolidation coefficient c v are obtained in relation to the results of uncontaminated samples. This generally indicates changes in the consolidation parameters of the soil medium in the presence of the tested contaminants. Methodologically, a delay in the onset of the steady-state phase of constant loading (CL) consolidation was observed in contaminated soils. This provides a rationale for programming the tests at lower values of the CL rate. At the same time, the unified model characterization of C CL–T CL allows us to assess the reliable nature of the results. This allows one to recommend CRL (constant rate of loading) tests as a reliable tool for determining the consolidation properties of cohesive soils in the design of soil isolation barriers.
