What Is Oxidized Bitumen 110/30?
Oxidized Bitumen 110/30 is a semi-solid blown asphalt manufactured by injecting hot air into base bitumen in a controlled process, which increases its softening point and stiffness compared to penetration grades. This transformation enhances thermal stability, chemical resistance, and adhesion performance, making it ideal for a variety of heavy-duty uses.
The designation “110/30” refers to:
Softening Point: 100–120°C (approximately 110°C at midpoint)
Penetration: 10–25 (0.1 mm) at 25°C
These values provide a balance of rigidity and flow characteristics suitable for static applications where high performance is required.
Applications of Oxidized Bitumen 110/30
Oxidized Bitumen 110/30 is widely used in industries where rigidity, heat tolerance, and surface protection are essential:
Construction and Waterproofing: Roofing felts and membranes, foundation damp-proofing, and concrete or structure sealing.
Protective and Industrial Coatings: Pipe coating and corrosion protection, tank linings and chemical barrier layers, and asphalt-based paints and coatings.
Road and Infrastructure: Paving sealants and overlays, crack repairs, and joint filling.
Specialty Applications: Anti-slip layer compounds in the piling industry, sound-dampening products, adhesives and mastics, insulation materials, and electrical laminate protection.
Beyond construction, this grade is also used across chemical, fuel, paint, lacquer, varnish, paper-pulp-board, and textile processing industries, as well as in automotive undercoating, where it provides waterproofing, dust protection, and noise reduction.
Oxidized Bitumen 110/30 vs. Other Oxidized Grades
Oxidized Bitumen 110/30 sits in the mid-hard range of the Oxidized Bitumen family, with a softening point (100–120°C) lower than the hardest grades like 115/15 or 150/5, but higher than softer grades such as 85/25 or 95/25. Its penetration range (10–25) and ductility (2 cm min) give it slightly more workability than the very hardest grades, making it a practical middle-ground choice for applications needing both thermal resistance and manageable flexibility.
Key Advantages of Oxidized Bitumen 110/30
Oxidized Bitumen 110/30 offers high purity without gilsonite or other impurities, excellent and permanent adhesion, low water absorption, and chemical stability. It provides flexibility combined with impact resistance, strong resistance to soil and cold stress, and high electrical resistance all conforming to ASTM standards for softening point and penetration.

Common Industries Using Oxidized Bitumen 110/30
This grade is widely used across the roofing and waterproofing industry, oil and gas pipeline coating, and adhesive and mastic manufacturing. Its combination of hardness and moderate flexibility also makes it a preferred choice for piling anti-slip compounds and sound-dampening products, where both rigidity and some degree of workability are needed.
Storage and Handling Recommendations
Oxidized Bitumen 110/30 should be stored in a cool, dry area away from direct sunlight and open flames. Its high softening point allows it to remain stable and solid at ambient temperature, simplifying long-term storage compared to softer bitumen grades. Before heating, the material should be broken into manageable pieces to ensure even, controlled heat distribution and avoid localized overheating that could affect performance.
