This bitumen is a semi-hard penetration grade with a penetration value between 40 and 50. Its thermoplastic property allows Bitumen 40/50 to soften at high temperatures and harden at lower temperatures, making it versatile for various weather conditions. The temperature-viscosity relationship of bitumen is influenced by the type of crude oil and refining method, affecting its performance parameters such as adhesion, rheology, durability, and application temperatures. Carbokim supplies this type of bitumen, which is used for producing hot mix asphalt in base layers, wearing courses, and road construction projects.

Carbokim ensures the penetration quality of Bitumen 40/50 as well as bitumen 80/100 through international inspections during loading and by providing batch test reports before shipment, in compliance with ASTM standards. This commitment to quality control guarantees the reliability and safety of the product for various construction applications.
