Abstract
In light of the current problems in the road construction industry related to technological violations during the laying of asphalt concrete mixtures and their negative impact on the physical and mechanical properties of the coating, special attention is paid to the quality of organic binder in asphalt concrete mixtures. In this article we will focus on studying the effect of polymer additives on the compaction of asphalt concrete mixtures.
Problems associated with technological violations during the laying of asphalt concrete not only reduce the durability of the pavement, but can also lead to serious operational problems. Our research focuses on solving these problems through the use of polymer additives that have the potential to increase the compaction of mixtures, hence improve the characteristics of the road surface.
Within the framework of the work, not only the influence of polymer additives on the physical and mechanical properties of asphalt concrete was considered, but also their influence on the stability and durability of the pavement was analyzed. The results obtained can serve as a basis for the development of effective strategies for improving the technology of laying asphalt concrete mixtures and improving the quality of road surfaces in general.
