Description of Bitumen 90/15
At the bitumen production reactor, during air oxidation, a mixture of Vacuum Bottom (VB) and Vacuum Silas (VS) feedstocks undergoes a controlled process at a temperature between 200-300°C. This process oxidizes the hydrogen atoms in the bitumen molecule, resulting in polymerization with higher hydrocarbons. The final product, oxidized bitumen 90/15, has a softening point of 90°C and a penetration value of 15 dmm.
Gold Bitumen guarantees the quality of its Bitumen 90/15 through international inspections and quality control (QC) testing, ensuring compliance with ASTM standards.
Uses of Bitumen 90/15
Grade 90/15 is widely used in industries such as:
- Chemicals, fuels, and coatings
- Road construction and pavement repair
- Roofing and waterproofing
- Adhesives and construction material additives
- Corrosion protection for metals
Application of Grade 90/15
Before application, Grade 90/15 must be heated to twice its softening point to achieve the required flow and viscosity. Surfaces should be clean, dry, and free of debris, curing products, or irregularities.
Storage/Handling of Oxidized
bitumen 90/15 has a shelf life of up to 10 years, even with repeated heating and cooling. Always refer to the Material Safety Data Sheet (MSDS) for safe handling instructions.
Packing of Bitumen Grade 90/15
Gold Bitumen offers multiple packing options to suit customer needs, including:
- Kraft bags
- Meltable plastic bags
- Drums
- Bulk containers
The product complies with ASTM standards, ensuring the desired softening point of 90°C and penetration value of 15 dmm.
Guaranty/Warranty of Blown Bitumen 90/15
GoldBitumen guarantees the quality of its oxidized Garid 90/15 through international inspections during shipment and strict quality control (QC) tests conducted before shipping. All products comply with ASTM/EN 13304:2009 standards.

FAQ
Here are the most common questions and answers about Bitumen 90/15:
A1: Bitumen 90/15 is a hard oxidized bitumen grade with a penetration value of about 15 (0.1 mm) and a softening point near 90 °C. It is designed for applications requiring high durability, rigidity, and heat resistance.
A2: This grade is used in roofing membranes, industrial flooring, pipe coatings, anti-corrosion protection, electrical industries (insulation materials), and specialized adhesives and sealants.
A3: For safe and efficient application, Bitumen 90/15 should be heated to approximately 200–220 °C. Continuous monitoring is required to avoid overheating and product degradation.
A4: It is available in 200 L steel drums, 25 kg kraft/meltable bags, jumbo bags, and in bulk (bitutainers or tankers), depending on project scale and logistics requirements.
A5: Yes. Bitumen 90/15 is manufactured in accordance with ASTM and EN standards. COA (Certificate of Analysis), MSDS, and third-party inspection reports (SGS, GeoChem) can be provided on request.
