Bitumen serves as the primary binding material in asphalt concrete mixtures for road construction Kazakhstan, where diverse climate demands specific properties durability and reliability. This study investigates potential of using bitumen grade 50/70 southern regions country, known extreme summer temperatures. While grades 70/100 100/130 are traditionally used, especially northern respectively, there is growing interest alternatives like due to supply challenges increased demand. However, concerns about its structural integrity under high thermal stress necessitate further analysis. The research compares performance through laboratory tests focusing on penetration, softening point, viscosity, adhesion. goal assess feasibility unique climatic conditions Kazakhstan explore modifications enhanced performance. findings will contribute optimizing
