The quality and durability of road pavements remain among the key challenges in modern road construction. The service life of asphalt concrete pavements largely depends on the mixture composition and the physical and mechanical properties of the bitumen used. In recent years, the increasing number of vehicles, particularly heavy trucks, has resulted in substantially higher traffic loads on road pavements. At the same time, pronounced temperature fluctuations between summer and winter contribute to the premature development of rutting, cracking, and other forms of pavement distress. Therefore, polymer modification of bitumen has emerged as a promising approach to improving the performance and durability of road pavements. This study investigated the physical and mechanical properties of asphalt concrete mixtures produced using bitumen modified with SBS (styrene-butadiene-styrene) polymer under laboratory conditions. The key performance parameters evaluated included Marshall stability, flow, density, air voids, voids in mineral aggregate (VMA), voids filled with bitumen (VFA), compressive strength, water resistance, and modulus of elasticity. The results were compared with those obtained from asphalt concrete specimens prepared using conventional paving-grade bitumen in order to assess the effect of polymer modification. The findings demonstrated that the incorporation of SBS polymer improved the mechanical stability of the asphalt concrete mixture and its resistance to deformation at elevated temperatures. It also enhanced resistance to water-induced damage and showed potential for extending pavement service life. The results of this study can serve as a basis for developing practical recommendations on the effective application of polymer-modified bitumen in the design, construction, and rehabilitation of road pavements under the sharply continental climatic conditions of Uzbekistan.
