This paper presents the results of a study on energy-efficient materials for polymer stone mastic asphalt (SMA) mixtures under the road and climatic conditions of Uzbekistan. The research evaluates the physical, mechanical, and performance properties of asphalt mixtures developed using polymer additives and fiber-reinforced components tailored to local climatic conditions. Laboratory test results demonstrate that the proposed energy-efficient materials significantly enhance resistance to deformation at high temperatures, improve cracking resistance at low temperatures, and increase moisture and fatigue resistance. The findings confirm the feasibility of using polymer stone mastic asphalt mixtures to improve energy efficiency and extend the service life of road pavements.
