Vehicle tire rubber is a valuable resource for reuse in the road construction segment

Abstract

The article presents an in-depth analysis of the used automobile tires accumulation and recycling subjects, as well as the possibility of its involvement in the closed cycle economy of the road construction segment. The issues of the society development concept in terms of the national and sectoral programs implementation that overlap with transdisciplinary approaches of geonics (geomimetics) in relation to the primary resources conservation and the secondary raw materials involvement are considered. The paper consistently outlines following issues: what a car tire is and used tires accumulation dynamics; the regulatory and legal framework in the tire recycling segment; methods of recycling worn-out tire products; the variability of rubber chips usage in road construction. The industry experience in rubber chips usage is highlighted, emphasising its use as mix modifiers in asphalt concrete composition. The information on the rubber modifiers and their key manufacturer is systematized. As part of the research, the technological foundations for the rubber modifiers for asphalt concrete mixtures production have been developed, based on the principles of man-made metasomatism and structural affinity, providing high performance of asphalt concrete in highways coating. It is noted that rubber modifiers are not only a response to morden environmental challenges, but also a key tool for durable, safe and economically viable road surfaces creating.
