The present paper is focused towards evaluation bearing capacity of subbase layer which is contaminated with Kerosene.
Seven series of model tests were performed using steel container (500*300*300mm). The bed of subbase was compacted in three layers inside the container; each layer was 100mm in depth. Circular footing 65mm in diameter resting on the bed of subbase were loaded incrementally up to failure. Different percentages of Kerosene (0%, 5%, 12% and 20%) were added, the first series consists of uncontaminated soil layer, the second series covers the model tests with added (5%, 12% and 20%) to the top subbase layer and third series covers the model tests with added (5%, 10% and 20%) to the top and second subbase layers. Each percentage was added separately. The results showed increase in ultimate bearing capacity; with increasing of Kerosene content up to 5% then a decrease with further increase of Kerosene content.
