摘要

Currently, scientists around the world are considering the possibility of using oily sludge as a secondary raw material for various purposes. It is known that the current methods in the country for processing some oil wastes are not economically efficient. The use of oily sludge as a secondary raw material seems to be one of the main directions in their use in the modification of bitumen and is of great practical importance. The research work studied the composition and properties of oily sludge from the Mangystau region and how they could potentially be used to produce modified bitumen. From a laboratory study, it was established that oily sludge can be used as a filler when modifying bitumen together with special modifiers. The samples obtained showed an improvement in the quality of the obtained mixture. This approach solves environmental problems related to oil waste disposal. The results of the study confirm that the selected oily sludges, due to their physical and chemical characteristics, are suitable for use in modifying road building materials. The presented basic technological scheme for modifying bitumen with oily sludge makes it possible to eliminate the problem of recycling oil waste with the production of a polymer-bitumen binder and allows the resource potential contained in oily sludge to be returned to the technological process.
