Bitumen 40/50

Bitumen 40/50

Understanding 

Bitumen 40/50 refers to bitumen with a penetration value ranging from 40 to 50 at standard test conditions. It is commonly used as a paving grade in various construction projects. Carbokim supplies this grade of bitumen, which is crucial for producing hot mix asphalt for bases, pavements, and road construction. 

Properties of Bitumen 40/50

It is a semi-hard penetration grade bitumen with a penetration grade between 40 to 50. Its thermoplastic property enables 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, impacting its performance parameters like adhesion, rheology, durability, and application temperatures.

Application of Bitumen 40/50

It extensive use in road construction and asphalt pavements due to its superior properties. Asphalt 40/50 is particularly suitable for hot mix asphalt production for bases and wearing courses. This grade of bitumen is favored in tropical regions where high air blowing and penetration are essential. Its quality remains intact even at high temperatures, ensuring reliable performance over time.

Guarantee and Safety Measures

Carbokim ensures the quality of bitumen penetration Asphalt 4050 through international inspections during loading and batch test reports before shipping to meet ASTM standards. This commitment to quality control guarantees the reliability and safety of the product for various construction applications.
