Bitumen 80/100
Bitumen Grade 80/100
Bitumen grade 80/100 is a dark brown to black material primarily obtained from the distillation of crude oil. This soft penetration grade bitumen is extensively used as a binder for mineral aggregates in road pavements. Additionally, it serves as a waterproofing material, a joint sealant, and is used in roofing applications. The main application of this grade of bitumen is in the production of hot mix asphalt for base and wearing courses.
Key Features of Bitumen 80/100
Bitumen 80/100 is highly adhesive and resistant to damage from water and oil spills, making it an ideal binder for asphalt. Asphalt is widely used for surfaces such as roads, car parks, and driveways due to its durability and resistance to environmental stressors.
Manufacturing Process of Bitumen 80/100
The production of Bitumen 80/100 involves refining crude oil through a distillation process. The crude oil is heated, and the lighter fractions are separated, leaving behind a residue that is further processed to achieve the desired penetration grade. The bitumen undergoes rigorous testing to ensure it meets the required specifications for penetration, softening point, viscosity, and other properties.
Softening Point and Penetration
Penetration grade bitumen 80/100 provided by ATDM is pure petroleum bitumen, produced from vacuum bottom by passing hot air. This bitumen is manufactured from the residue of crude oil after cracking and removing hydrocarbons. The penetration grade bitumen 80/100 has a penetration range between 80 to 100 desi-millimeters and a softening point between 42 to 50°C. Its thermoplastic properties make it similar to synthetic resin materials, softening when heated and hardening when cooled. Bitumen 80/100 exhibits very strong viscosity compared to other grades.
Quality Guarantee and Warranty
ATDM guarantees the quality of bitumen 80/100 by arranging international inspectors to check the quality and quantity during loading to the vessel. Quality control is ensured through batch test reports before shipping, meeting ASTM/EN 12591 standards.

Differences Between Bitumen 80/100 and 60/70
The primary differences between Bitumen 80/100 and 60/70 lie in their penetration values, softening points, viscosity, and application suitability. These factors determine their performance in different environmental conditions and traffic scenarios.
Penetration Grade Explained
Penetration grade measures the depth a standard needle penetrates the bitumen sample under specific conditions of temperature, load, and time. This measurement helps classify bitumen into various grades. Bitumen 80/100 has a penetration value between 80 and 100, indicating it is softer, while Bitumen 60/70 has a value between 60 and 70, showing it is harder.
Softening Point
The softening point of bitumen is the temperature at which it becomes soft enough to flow. Bitumen 80/100 has a lower softening point compared to Bitumen 60/70. This characteristic means Bitumen 80/100 will become pliable at lower temperatures, making it more suitable for cooler climates, whereas Bitumen 60/70, with its higher softening point, is better for hotter regions.
80/100 grade percentage
Generally this 80/100 means 80 to 100 not 80 from 100!Most of people make mistake on the grade and thinking it is percentage in bitumen while it is wrong and showing penetration number only.
