Assessment of Bearing Capacity of Subbase Contaminated with Kerosene


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.
