1) Introduction

Introduction: Oxidized Bitumen Grades Explained

Oxidized bitumen grades explained help engineers and contractors select the most suitable material for different construction and industrial applications. These grades consider properties like softening point, penetration, ductility, and viscosity, ensuring projects withstand environmental and traffic stresses.

Proper grading of oxidized bitumen allows for enhanced durability in roads, roofing, and waterproofing applications. As infrastructure and building demands increase globally, selecting the correct oxidized bitumen grade remains a critical factor in long-term project performance.

Transitioning from general grading principles, the next section explores what oxidized bitumen is, its properties, and benefits for construction and industrial use.

Oxidized Bitumen Grades Explained

SEO Snippet: Oxidized bitumen grades are classified based on softening point, penetration, and viscosity to meet industrial and construction needs.

Oxidized bitumen is graded to match specific engineering requirements. Softening point is a major criterion, representing the temperature at which the material becomes malleable. Lower grades with softer points are ideal for flexibility in road joints, while higher grades offer heat and weather resistance for roofing and waterproofing.

Penetration value also influences grading. It measures hardness, where lower penetration indicates stiffer bitumen, suitable for high-stress pavements. Other factors include ductility, viscosity, and solubility, affecting flexibility, application, and bonding with aggregates.

NovinTrades Market View and Forecast: Demand for high-grade oxidized bitumen in 2025 is increasing due to infrastructure expansion, particularly in Asia and the Middle East.

3) What is Oxidized Bitumen

What is Oxidized Bitumen

SEO Snippet: Oxidized bitumen, or air-blown bitumen, is modified to improve stiffness, temperature resistance, and adhesion for industrial applications.

Oxidized bitumen, also called blown bitumen, is produced by exposing bitumen to controlled air at high temperatures. This process increases stiffness, softening point, and adhesive properties. The degree of oxidation determines its final properties, allowing customization for roads, roofing, and industrial waterproofing.

Advantages include superior rutting resistance in hot climates, improved bonding with aggregates, and enhanced waterproofing for roofing. Limitations involve reduced flexibility and higher handling difficulty in colder regions.

4) Bitumen Grades Explained

Bitumen Grades Explained

SEO Snippet: Bitumen grades—penetration, viscosity, performance, and oxidized—ensure appropriate selection for roads, roofing, and waterproofing projects.

Bitumen is categorized based on its properties and intended use:

• Penetration Grade (PG): Hardness-based, measured by needle penetration depth. Softer grades for flexible roads; harder grades for high-stress pavements.
• Viscosity Grade (VG): Kinematic viscosity at specific temperatures, important for asphalt mixing and coating aggregates.
• Performance Grade (PG): High and low-temperature performance, reducing pavement distress (e.g., PG 64-22).
• Oxidized Bitumen: Air-blown for higher stiffness, temperature resistance, and adhesion.
• Cutback Bitumen: Solvent-modified for easy handling while maintaining adhesive properties after evaporation.
