Abstract
The paper examines pathways to greening the production and paving technologies of asphalt concrete through the use of energy-saving additives that enable lower operating temperatures, with the aim of reducing energy consumption and CO₂ emissions. An analysis is provided of contemporary approaches to so-called warm mix asphalts (WMA), which deliver the required pavement performance at mixing temperatures 30–40 °C lower than conventional hot mixes. As part of the study, a practical case is presented for placing WMA on Verbova Street, where a dedicated temperature-reducing additive was employed. The outcomes of implementation are evaluated, including compaction process indicators, the pavement’s physico mechanical properties, fuel savings, and reductions in greenhouse-gas emissions. It is shown that energy saving technologies in asphalt concrete can substantially decrease energy demand and environmental impact without degrading pavement quality. Conclusions are drawn regarding the economic and environmental efficiency of the technology, and prospects are outlined for its wider deployment in road construction.
