ROAD INFRASTRUCTURE AND ECOLOGICAL CHALLENGES

Abstract

Road infrastructure is one of the key foundations of modem economic and social development; however, its construction and operation have significant impacts on the environment. This paper discusses the major environmental challenges associated with road infrastructure, including air pollution, traffic noise, and the contamination of water and soil caused by surface runoff. Particular attention is given to vehicle emissions, particles generated by pavement and tire wear, as well as the risks associated with the release of heavy metals and petroleum products into the environment. Modern engineering approaches aimed at reducing environmental impacts are presented, including low-noise and permeable pavements, the use of recycled materials, efficient drainage systems, green infrastructure, and intelligent transportation systems. The paper also reviews international experience and the principles of sustainable road infrastructure development. It emphasizes the importance of integrating environmental requirements into all stages of road planning, design, construction, and operation. Such an approach makes it possible to maintain the functional efficiency of transport infrastructure while reducing adverse environmental impacts, improving urban ecological conditions, enhancing the resilience of road systems to climatic and technological pressures, and ensuring better protection of public health in the long term.
