Abstract
The geotechnical properties of soils polluted by petroleum derivatives (such as diesel) are significantly
altered after contamination. However, different treatment methods can improve the properties of these
soils. This study examines the effect of diesel contamination of clay taken from the region of Sidi
Hadjres, Wilaya of M’sila. The experimental program undertaken includes compaction and
compressive strength tests. The tests were carried out on natural soil (without contamination) and soil
contaminated with diesel in different concentrations (3.6, and 9%). The study also considers the
potential to improve the mechanical performance of contaminated clay by its treatment with sand and
lime. The results obtained showed that diesel modifies the mechanical properties of this clay.
However, adding lime and/or sand to contaminated soils significantly contributes to regaining the
natural properties of the soil with a low lime content
