Large-scale oil pollution of the environment, as well as the increasing volume of oil production in the Republic of Kazakhstan brings to the forefront the problem of localization, elimination of pollution and development of the method of utilization of oil-contaminated soils. Consequently, it is necessary to develop more convenient and cheaper ways of utilization of oil-contaminated soils. To solve the problem of utilization of oil contaminated soils, a number of studies have been carried out in recent years on the disposal of oil contaminated soils. In the work investigated the level of “background value” of the content of oil hydrocarbons in the oiled soil of industrial zone Oil and gas production department-1 (OGPD-1) of JSC “Ozenmunaigas”. It was found that on average per 1 kg of oiled soil the content of oil hydrocarbons is 119.294 g, in percentage terms 13%. The level of pollution of oiled soil of industrial zone of OGPD-1 of JSC “Ozenmunaigas” belongs to the third level of background value, self-cleaning ability of soil is very heavy. Nine new formulations of the composition for soil strengthening on the basis of oiled soil of industrial zone OGPD-1 of JSC “Ozenmunaigas” were developed. The test results showed that the reinforced soils on the basis of oiled soils of industrial zone OGPD-1 of JSC “Ozenmunaigas” have strengths M20 and M10. According to the code of regulations СR RK 24-75 and standard ST RK 973-2015 it is recommended to use the new reinforced soil composition in the construction of unpaved roads in the bottom layer of bases or as an additional base layer for III, IV, V categories of highway. The developed method of utilization of oiled soils makes it possible to use oiled soil in the construction of in-field unpaved roads, allows to expand the raw material base for obtaining construction materials for road construction, solves one of the most important environmental problems in the field of soil and atmosphere protection.
