What is Oxidized Bitumen 90/50?
Oxidized Bitumen 90/50 is a specially processed form of bitumen. Industry leaders call this material as blown asphalt or hard bitumen as well. It is widely used in the construction industry, particularly in road construction and various waterproofing applications. This high-quality bituminous product is created through a controlled oxidation process, which enhances its physical properties and makes it suitable for a range of purposes.
Application and Production Details
Oxidized Bitumen 90/50 is renowned for its exceptional performance in road construction and waterproofing projects. To learn more about these industries, you can check below:
Road Construction: Oxidized Bitumen 90/50 serves as a fundamental component in asphalt mixtures. It contributes to the durability and longevity of road surfaces. Its superior binding properties make it an ideal choice for high-traffic roads.
Roofing and Waterproofing: This bitumen grade is a preferred choice for waterproofing applications due to its high softening point and resistance to temperature fluctuations. It effectively seals roofs, preventing water leakage and ensuring long-lasting protection.
Production Process of Oxidized Bitumen 90/50
The production of Oxidized Bitumen 90/50 involves a meticulous oxidation process. Here’s a brief overview of the production steps:
Selecting the Raw Material: High-quality bitumen with suitable properties is selected as the starting material.
Air Blowing: The selected bitumen is subjected to controlled air blowing at elevated temperatures. This process introduces oxygen, which alters the bitumen’s molecular structure, resulting in increased hardness and improved thermal stability.
Quality Control: Rigorous quality control measures are employed throughout the production process to ensure that the final product meets the specified Oxidized Bitumen 90/50 standards.
Technical Advantages of Oxidized Bitumen 90/50
Oxidized Bitumen 90/50 offers several technical advantages that make it a preferred choice in construction and waterproofing:
High Softening Point: This bitumen has an elevated softening point. This ensures excellent performance under high-temperature conditions.
Enhanced Durability: Its increased hardness and resistance to deformation make it highly durable, particularly in road construction.
Improved Thermal Stability: Blown asphalt 90/50 exhibits superior thermal stability, making it suitable for applications where temperature fluctuations are common.
How to Apply Oxidized Bitumen 90/50
Applying hard bitumen 90/50 requires careful consideration and adherence to best practices. Here are some guidelines for application:
Surface Preparation: You should ensure that the surface is clean, dry, and free from contaminants before applying the bitumen.
Heating: You should heat the 90/50 material to the appropriate temperature for easy application, typically between 160°C to 180°C.
Application Method: You should apply the bitumen evenly using a suitable method, such as spraying or brushing.
