The oil, gas and petroleum industries are considered as a potential source of pollution. Oil contamination has a negative impact on environment. The engineering properties of soil will get adversely affected due to oil contamination making it unsuitable for construction purposes. A good knowledge of change in geotechnical properties of soil due to contamination is required for providing proper recommendations regarding its use in the construction activities. The behaviour of different soils after oil contamination will be different based on the constituents present in it. This paper discusses effect of oil contamination on lateritic soil. Used engine oil was added to soil in the amount of 0%, 2%, 4% and 6% by weight to artificially contaminate the soil, and the variation in properties was identified. The effect of contamination was studied based on the change in consistency limits, compaction characteristics, CBR value and shear strength parameters. |
