The work is devoted to a comprehensive technical and economic justification of the use of rubber crumb in road construction as one of the innovative directions of increasing the durability and quality of roads. The work considers modern approaches to the use of secondary rubber raw materials obtained by recycling worn-out automobile tires, which is currently an important component of European and global sustainable development practice. Based on the generalization of the technical characteristics of modified asphalt concrete mixtures, the influence of rubber crumb on the physical and mechanical properties of the road surface is analyzed, in particular on increasing elasticity, resistance to cracking, rutting resistance and improving wheel adhesion to the road surface. Special attention is paid to reducing traffic noise and increasing the comfort of movement in urban environments.
The article also highlights the environmental benefits of the technology associated with the utilization of waste tires, reducing the load on solid waste landfills and developing the secondary recycling market. Given the need to minimize the negative impact on the environment, the use of rubber crumb is considered an effective tool for the environmental modernization of the road industry.
The economic analysis includes a comparison of traditional and modified technologies according to the criteria of construction cost, service life and need for repairs. It is shown that, despite a slight increase in initial costs, road surfaces with rubber crumb provide significant savings over the life cycle of the road due to an increase in service life and a decrease in the frequency of repair work. An assessment of economic efficiency is presented using indicators such as net present value, profitability index and payback period.
It is concluded that the use of rubber crumb is a promising direction for the development of road construction in Ukraine, which combines technological, economic and environmental advantages.
