Abstract

Environments such as Air, Water and Soil are suffering from many issues, in addition to that soil has other problems specially soft soil problems. And either contaminated soils problems and soft soil issues should be minimized. On the other hands, Iraq is one of the petroleum countries which produce high quantities of oil and as well-known each production process has a by-product, Oil produce very high amounts of waste materials. Waste oil has a bad influence on the environment specially on the soil, and the only way to reduce this bad effect by recycling waste oil. Waste oil has a bad influence on the environment specially on the soil. The key objective of this article is to investigate the reflection of waste oil the mechanical, physical and chemical characteristics of the intact clay soil. Geotechnical tests for example (Atterberg limits, compaction, un-confined compressive strength (UCS) and consolidation tests were conducted by using (2, 5 and 10)% of recycle oil by the weight of dry soil. The results of experiments show an increasing in the permeability and compressibility, while decreasing the strength and the young modules due to increase the oil content, where the soil tend to behave as sponge by increasing the pollutants proportion (oil ratio). As well as the optimum moisture amount, maximum dry density, and the plasticity index for clay soil were decreased with increasing the pollutants proportion (oil ratio).The chemical results detected increasing of gypsum content, tri-sulphur content, total deposit salt (TDS) and organic matter with increasing oil content.
