Based on scientific research and experimental tests, it has been proved that solid waste from oil fields
in the Kyzylorda region based on asphalt resin paraffin sediment (ARPS) is close and binding in its chemical
composition to the main component of the asphalt-concrete mixture of the road surface. And the most effective
method of disposal and neutralization of oil waste was chosen.
The ARPS formed from the use of oil at the Kumkol field was studied, which includes asphaltenes 3 ... 8%;
resins-13 ... 20%; fats-34...65%; mechanical impurities-20...49%; water-1...5%.
In this article, it is proposed to develop an asphalt-concrete technology based on asphalt-resinous paraffin
deposits. The issue of increasing the reserves of raw materials for the production of durable asphalt concrete and
reducing the amount of oil-containing waste in the fields due to the sale of solid oil-containing waste will be
considered. Based on the study, the composition of asphalt-resinous paraffin deposits was analyzed by IR
spectroscopy. The infrared (IR) absorption spectrum was captured in the IR-Fourier spectrometer IR Prestige-21.
The absorption spectra of asphalt-tar-paraffin deposits recorded by the IR spectrometer show the structure of
hydrocarbons in the methyl (2954-2852 cm-1), methylene (1463-1377 cm-1), and methine (721 cm-1) groups. The
analysis shows that the composition of solid oil waste generated at the fields consists mainly of paraffin
hydrocarbons.
The results of the study showed the suitability of asphalt-resinous paraffin deposits for use as organic binders to
dense asphalt concrete of type" B " grade III for IV-V road climatic zones recommended for applying top layers of
coating on roads of technical category IY.
Replacing scarce commercial bitumen with oil waste will significantly reduce the cost of commercial products,
as well as simplify the process of preparing the mixture and prevent environmental pollution with harmful substances
released from oil.
