Abstract
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.
