Oxidized Bitumen 90/15

Understanding oxidized bitumen 90/15

Oxidized bitumen 90/15 is a specially formulated construction material with specific thermal and performance characteristics. Here’s a detailed description:

Production Process: Oxidized bitumen 90/15 is produced through a controlled oxidation process of a mixture of Vacuum Bottom (VB) and Vacuum Silas (VS) feedstock in a bitumen production reactor. Under precise conditions of pressure and temperature (typically between 200-300˚C), hydrogen atoms in bitumen molecules oxidize with atmospheric oxygen, leading to a polymerization reaction. This process results in a bitumen product with higher softening points and lower penetration compared to pure bitumen. Oxidized bitumen 90/15 has a softening point of 90°C and a permeability of 15, indicating its stiffness and resistance to penetration.
Plasticity and Thermal Amplitude: Oxidized bitumen is specially formulated to exhibit great thermal amplitude, meaning it can withstand a wide range of temperatures without losing its structural integrity. It remains flexible at low temperatures, preventing cracking and brittleness, while also maintaining stability and preventing sagging at high temperatures. This plasticity makes it suitable for various construction applications where temperature fluctuations are common.
Versatility and Application: Oxidized bitumen 90/15 is a versatile construction material that can be applied in various types of projects. Its excellent adhesion properties allow it to be used in different construction scenarios, including road construction, pavement maintenance, roofing, waterproofing, and civil engineering works. Its stiffness and durability make it particularly suitable for applications requiring high-performance characteristics.

How to apply:

The application of oxidized bitumen 90/15 requires careful preparation of surfaces and appropriate temperature conditions for optimal performance. Here are the key considerations:

Heating: Oxidized bitumen 90/15 needs to be heated to a temperature double that of its softening point to achieve the required flow and viscosity for application. This ensures that the bitumen can be properly spread and adhered to the surface.
Surface Preparation: Before applying oxidized bitumen 90/15, surfaces must be thoroughly cleaned, dry, and free of any loose particles, debris, or contaminants. This preparation ensures proper adhesion and bonding of the bitumen to the substrate.
Removal of Formwork and Curing Products: Any formwork or curing products previously applied to the surface should be removed before the application of oxidized bitumen 90/15. This allows for direct contact between the bitumen and the substrate, ensuring effective sealing and waterproofing.
Surface Smoothness: Surfaces should be free of irregularities, slurry, or other imperfections that may affect the application and performance of the oxidized bitumen. Smoothing out any uneven areas or filling in gaps can help ensure a uniform application and consistent coverage.
Temperature Control: While heating the oxidized bitumen to the appropriate temperature is essential, maintaining the temperature during application is also crucial. Consistent temperature control helps ensure proper flow and viscosity of the bitumen, allowing for uniform coverage and adhesion to the surface.
Safety Precautions: When heating and handling oxidized bitumen 90/15, appropriate safety precautions should be taken to prevent accidents or injuries. This may include using protective equipment such as gloves, goggles, and masks, as well as following proper heating and handling procedures.

By following these guidelines for surface preparation, temperature control, and safety precautions, oxidized bitumen 90/15 can be effectively applied for various construction and waterproofing applications, providing durable and reliable protection against moisture and environmental elements.
