В данной статье рассматриваются возможности использования переработанных материалов для модификации битумных вяжущих в рамках концепции циркулярной экономики. Для модификации битума использованы полимерные отходы и резиновая крошка. Проведенные исследования показали, что данные добавки улучшают термостойкость, эластичность и устойчивость битума к окислению. Кроме того, установлено, что эксплуатационные характеристики модифицированного битума значительно улучшаются: снижается температура хрупкости и повышается температура размягчения. Оптимальные концентрации модификаторов были определены, а их влияние на структуру битума изучено. В результате исследования смесь БНД 60/90 («ПМХЗ» ТОО) + 6% FPMB показала наилучшие результаты по термостойкости и твердости после окисления, что делает ее пригодной для использования в дорожных покрытиях с высокими эксплуатационными требованиями. Полученные результаты подтверждают эффективность внедрения переработанных материалов в дорожное строительство, демонстрируя их экологические и экономические преимущества. В соответствии с принципами циркулярной экономики использование переработанных полимеров способствует рациональному потреблению природных ресурсов, сокращению отходов и обеспечению экологической устойчивости. Инновационные подходы в дорожном строительстве позволяют создавать прочные и долговечные покрытия. Кроме того, данное исследование предлагает инновационные методы модификации битума, что способствует улучшению качества строительных материалов и увеличению их долговечности. Таким образом, использование переработанных материалов позволяет повысить прочность дорожных покрытий, снизить негативное воздействие на окружающую среду и достичь целей устойчивого развития.

This article explores the potential of using recycled materials for modifying bituminous binders within the framework of the circular economy concept. Polymer waste and crumb rubber were used for bitumen modification. The conducted research demonstrated that these additives enhance the thermal stability, flexibility, and oxidation resistance of bitumen. Furthermore, it was found that the performance characteristics of modified bitumen significantly improve: the brittle fracture temperature decreases, while the softening temperature increases. The optimal concentrations of modifiers were determined, and their effect on the bitumen structure was studied. As a result of the study, the BND 60/90 («POCR» LLP) + 6% FPMB mixture showed the best results in terms of thermal stability and hardness after oxidation, making it suitable for use in high-performance road pavements. The obtained results confirm the effectiveness of integrating recycled materials into road construction, highlighting their environmental and economic benefits. In line with the principles of the circular economy, the use of recycled polymers promotes the rational consumption of natural resources, waste reduction, and environmental sustainability. Such innovative approaches in road construction enable the creation of durable and long-lasting pavements. Moreover, this study proposes innovative methods for bitumen modification, contributing to the improvement of construction material quality and durability. Thus, the use of recycled materials helps enhance the strength of road pavements, minimize environmental impact, and achieve sustainable development goals.
