Sabkha soils mixed with oil lake residues – Reuse of a waste material.

The work presented in this paper forms part of an experimental project to assess the viability of stabilising Sabkha soils with oil lake residues. The Sabkha soils investigated were from south Kuwait. Specimens were prepared by mixing the dry Sabkha soil samples with different percentages of oil residues by weight. The results presented include basic physical properties such as grain size distribution, consistency limits, compaction and permeability. Results indicated that the addition of oil residues improves the performance of the Sabkha soils. Maximum dry density increases with the addition of up to 8% oil residues and reduces with more addition. Soil gradations become coarser as the percentage of oil lake residues increases. Permeability and plasticity decreases and plasticity index was slightly affected.
