Bitumen 70/100

Bitumen grade 70/100 Overview

Bitumen grade 70/100 is a premium paving-grade bitumen, widely used in road construction and the production of hot-mix asphalt. Produced through the fractional or vacuum distillation of crude oil, this bitumen offers exceptional performance. Specifically, the grade 70/100 indicates the penetration range at 25°C, which falls between 70 to 100 mm/10, reflecting its hardness. Due to its impressive properties, Bitumen grade 70/100 ensures long-lasting, durable pavements, making it an ideal choice for demanding roadworks and asphalt production.

Production Process of Bitumen grade 70/100

ATDM produces bitumen 70/100 using state-of-the-art technology to achieve optimal quality. Initially, the bitumen is derived from the vacuum bottom of crude oil, where we effectively remove hydrocarbons to enhance the material’s properties. This results in bitumen with strong viscosity and thermoplastic characteristics. As a result, the material softens at higher temperatures and hardens as it cools. This temperature-sensitive behavior plays a critical role in ensuring reliable performance in varying environmental conditions, making bitumen 70/100 highly versatile.

Properties and Benefits of Bitumen grade 70/100

The bitumen 70/100 features strong viscosity, ensuring excellent performance across various applications. With a softening point ranging between 43°C and 51°C, along with a penetration range of 70 to 100 desi-millimeters, this bitumen is highly resilient. Furthermore, its high viscosity ensures superior adhesion, making it ideal for long-lasting road construction. In addition, Bitumen grade 70/100 maintains durability under different weather conditions, offering excellent resistance to deformation, which is essential for maintaining high-quality roads.

Applications of Bitumen grade 70/100

Bitumen 70/100 is perfectly suited for road construction and repair, especially when mixed with other materials to form high-quality hot-mix asphalt. Moreover, it is commonly used for both base layers and wearing courses in asphalt pavements, ensuring that roads are durable and resistant to wear and tear. Additionally, bitumen 70/100 adapts well to diverse climate conditions, making it a versatile choice for regions with both high and low temperatures. This flexibility makes it the ideal solution for various roadwork applications, from routine repairs to large-scale road construction projects.
