Introduction

When it comes to road construction and maintenance, one essential ingredient that plays a crucial role in ensuring the longevity and resilience of asphalt is oxidized bitumen 115/15. This specialized bitumen grade, also known as blown bitumen, is a key component that significantly enhances the performance and durability of asphalt mixtures, making it an indispensable choice for various infrastructure projects.

Oxidized bitumen 115/15 is produced by a controlled process of air-blowing, which involves passing air through hot bitumen to increase its viscosity and stiffness. This transformation gives the bitumen specific characteristics that make it ideal for demanding applications where high-quality asphalt is required. Here are some key advantages of oxidized bitumen 115/15:

• Improved Durability: The oxidation process makes bitumen more resistant to temperature variations, water, and other environmental factors. This translates to increased durability and reduced cracking, which is particularly important for roads exposed to heavy traffic and extreme weather conditions.
• Enhanced Aging Properties: The oxidation of bitumen improves its aging properties, allowing the asphalt mixture to maintain its structural integrity over an extended period. This is essential for ensuring the longevity of roads, reducing maintenance costs, and minimizing disruptions.
• High Softening Point: Oxidized bitumen 115/15 has a higher softening point compared to regular bitumen, making it suitable for areas with high temperatures. It helps prevent rutting and deformation in hot climates, making it an excellent choice for regions with challenging weather patterns.
• Adhesion and Cohesion: Oxidized bitumen 115/15 offers excellent adhesion and cohesion properties, ensuring that asphalt mixtures adhere well to aggregates and remain intact under heavy traffic loads. This is essential for maintaining a smooth and stable road surface.
