Bitumen 85/40

Description of blown bitumen 85/40

Blown bitumen 85/40 is a semi-solid grade of pure petroleum bitumen that results from blowing bitumen 60/70 with hot air. This process significantly alters the physical properties of the bitumen, making it suitable for a wide range of applications in the construction industry. Specifically, the numbers 85/40 represent the softening point and penetration values of the bitumen. The softening point, measured by the Ring and Ball method (ASTM D36), and the penetration value, determined by ASTM D5 or IP49, provide crucial information about the material’s characteristics. Therefore, blown bitumen 85/40 delivers consistency and reliability for various construction needs.

ATDM ensures the quality of blown bitumen 85/40 by conducting rigorous inspections throughout the production and loading process. First, international inspectors verify the quality and quantity of the product during loading. Additionally, ATDM oversees production with batch test reports before shipping. These actions ensure the product complies with ASTM standards, so customers can trust its performance.

Uses of bitumen 85/40

Blown bitumen 85/40 has diverse uses across multiple industries. For example, it plays a critical role in sectors such as chemical, fuel, paint, lacquer, and textile industries. Moreover, the construction industry widely uses it for road construction, pavement repair, and crack sealing. In addition, it has applications in civil engineering, particularly for sealing, insulating, and waterproofing buildings. As an added benefit, it works as a highly effective adhesive, construction material additive, and dust-binding agent.

bitumen 85/40 also proves invaluable for corrosion protection. Specifically, industries use it in asphalt-based paints to protect metals, in the lining of public works structures, and as a base for synthetic turf. Furthermore, it plays a key role in waterproofing applications, including pipe coating, hydraulic projects, paint manufacturing, caulking, mastics, and damp-proofing.

The automotive industry also benefits from blown bitumen 85/40, particularly for vehicle undercoating. When applied to vehicles, it provides excellent protection against water, dust, and noise, contributing to longer-lasting and more durable automotive parts.

Application of blown bitumen 85/40

Before using bitumen 85/40, heat it to double its softening point to achieve the desired flow and viscosity. Additionally, make sure that the surfaces to be treated are dry, clean, and free from loose particles, formwork, curing products, and irregularities. This ensures a better application and stronger adhesion, leading to a more durable and effective finish.

Storage and handling of bitumen 85/40

Blown bitumen 85/40 has a shelf life of up to 10 years and can withstand multiple heating and cooling cycles without losing its properties. However, it’s important to follow proper handling procedures, as detailed in the Material Safety Data Sheet (MSDS).

Packaging of bitumen 85/40

ATDM offers a variety of packaging options to suit customer needs, including Kraft bags, meltable plastic bags, drums, and bulk deliveries. ATDM manufactures blown bitumen 85/40 by blowing bitumen 60/70 with hot air until it meets the desired specifications. After this process, the bitumen is packaged according to customer preferences. The grade 85/40 refers to a softening point of 85°C and a penetration value of 40 decimillimeters. ATDM produces this product in full compliance with ASTM standards, ensuring high quality and performance.
