Utilization of Oil Wastes for Production of Road-building Materials

Abstract

<p>The pollution of environment by oil spills in the process of extraction, refining and transporting of oil is an important ecological problem of oil industry. Composition and properties of the oil sludge and il contaminated soil taken from the area of Zhetybai – Uzen – Atyrau pipeline failure have been investigated aiming at development of oil waste utilization methods. The offered thermal method of organic fraction extraction allows to decrease the organic fraction content by 15–20 %. It is shown that the recovered oil may be used for the bitumen production, and the solid residue – as a component of cold asphalt concrete.</p>

Environmentally Friendly Technologies Based on Combustion Processes

“…From comparative analysis of the data of Table 6 it is evident that physical and mechanical characteristics of asphalt mixtures meet the requirements of State standard 9128-84 [14]. In the beginning the oil residues have diluting effect on the used bitumen and with time in result of oxidation in the open air and bitumen viscosity increasing the strength of asphalt cover increases.…”

“…of areas [13,14]. The oil sludge resulted of oil waste processing, stable nondistruct emulsions production, reservoirs scarfing, agents discharges and other oil mining and processing operations should be unloaded into the special waste storage precipitators.…”
