The relevance of this study is conditioned by the high degree of importance of creating the latest modifications of the polymer–bitumen binder for the manufacture of high-quality asphalt concrete, for its subsequent use in the construction of motorways and concrete pavements of airfields. In this context, the purpose of the study is to obtain new, scientifically substantiated technological solutions for the development and practical application of effective nanomodified polymer-bitumen binders (PBBs) that can improve the operational characteristics and duration of practical use of asphalt. The study results clearly demonstrate the fact that carbon nanotubes (CNTs) are a stabiliser and an ageing inhibitor of polymer–bitumen binders (PBBs), while contributing to a decrease in the intensity of its operational destruction over time by more than 10 times relative to the compositions of PBB with structuring additives, which is essential in the preparation and practical use of asphalt concrete for the construction of motorways and airfields. The results obtained are of significant importance for developers of modern technologies for manufacturing asphalt concrete for road construction, and road maintenance workers who professionally solve the problems of road maintenance, applying the latest practical developments in the field of road construction and repair in their activities.
The relevance of the subject matter is conditioned by the importance of resolving the issues of practical use of ash and slag waste to create a high-quality road surface. The aim of the study is to determine the main promising areas for the use of ash and slag waste in creating a reliable road surface structure during roadway repair. The leading approach in this study is the systematic analysis of the entire complex of issues submitted for consideration, in the context of assessing the importance of the prospects for the practical use of waste in road construction to create a high-quality road surface and the prospects for reducing the cost of its maintenance and possible repair. It has been found that the practical use of ash and slag waste can significantly increase the strength of the road surface and increase its service life. Also, it is stated that the use of ash and slag mixture allows for achieving a significant reduction in the cost of building materials. It is concluded that the activating additives should be introduced to reduce cement consumption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
