Bitumen 30/40

Understanding Bitumen 30/40

Bitumen 30/40, also known as Semi-Hard penetration grade bitumen, is extensively used in road construction and repair projects. This grade of bitumen is particularly suitable for producing high-quality Asphalt pavements, meeting stringent specifications and ensuring durability.

Manufacturing Process and Quality Assurance

Penetration Grade Bitumen 30/40, supplied by reputable companies like Carbokim, is derived from the fractional or vacuum distillation of crude oil. This ensures a consistent quality and performance level, essential for road applications. Carbokim guarantees the quality of its bitumen by employing international inspectors to oversee the loading process and conducting batch test reports before shipping to meet ASTM standards.

Key Properties of Bitumen 30/40

One of the key characteristics of Penetration Grade Bitumen 30/40 is its thermoplastic nature. This property allows the bitumen to soften at elevated temperatures, making it ideal for hot mix asphalt production, while hardening at lower temperatures to withstand varying climate conditions. The unique temperature-viscosity relationship of this grade of bitumen plays a crucial role in its adhesion, rheology, durability, and application temperatures.

Applications and Suitability

Carbokim Asphalt 30/40 finds specialized applications in areas such as airport runways and high-traffic volume roads, especially in coastal regions where temperature differentials can be significant. Its suitability for hot mix asphalt production, particularly for bases and wearing courses, makes it a preferred choice for road construction projects.

Packaging Options

Penetration Grade 30/40 is commonly packaged in new steel drums ranging from 150 to 220 kilograms, as well as 1MT and 500kg Jumbo Bags or 300kg Bitubags. Additionally, bulk packaging options are available for direct transportation via trucks, ensuring convenience and efficiency in handling and usage.
