Introduction: Grade of Bitumen 80/100 Means
The grade of bitumen 80/100 means that it is a conventional penetrating bitumen, commonly used in asphalt and road construction. This grade is ideal for hot mix asphalt due to its stability and performance under varying temperatures.
Bitumen 80/100 is also utilized in parking lots, airport runways, pedestrian pathways, and roofing applications, thanks to its waterproofing properties. Globally, around 102 million tons of bitumen are consumed annually, with nearly 85% used for road paving and the remainder in roofing and construction sealing applications.
As a semi-solid hydrocarbon, bitumen is derived from crude oil refining, where lighter fractions are separated. Despite common misconceptions, bitumen is not the same as coal tar or petroleum pitch. Its refined form ensures consistent quality for industrial use.
Transitioning to the next section, understanding the specific applications of bitumen 80/100 can clarify why it remains a preferred choice worldwide.
LSI Keywords: conventional bitumen, road grade bitumen, asphalt binder, paving bitumen, refined hydrocarbon, hot mix asphalt
2) Applications of Bitumen 80/100
The applications of bitumen 80/100 cover road construction, roofing, and industrial sealing. Its high penetration value allows flexibility in asphalt mixes, which reduces cracking in varying temperatures.
SEO Snippet: Bitumen 80/100 is primarily used in roads, runways, parking lots, and roofing due to its versatile performance.
Section Summary: The grade is ideal for hot mix asphalt, used globally in roads, airports, and pedestrian pathways. Roofing also utilizes this grade for waterproofing. Specialized blends with polymers enhance performance.

Novin Trades Market View and Forecast: The demand for bitumen 80/100 remains steady due to ongoing infrastructure projects, particularly in developing regions of Asia and the Middle East.
3) Difference Between Bitumen, Coal Tar, and Petroleum Pitch
The difference between bitumen, coal tar, and petroleum pitch is significant in terms of chemical composition and origin. Bitumen is petroleum-derived, while coal tar comes from heating coal and pitch from cracking petroleum fractions.
SEO Snippet: Bitumen is distinct from coal tar and petroleum pitch, each having unique origins, chemical makeup, and industrial uses.
Section Summary: Refined bitumen is a semi-solid hydrocarbon, coal tar is a by-product of coal gasification, and petroleum pitch is residue from petroleum cracking. Confusing these substances can lead to incorrect applications and safety issues.
LSI Keywords: petroleum bitumen, coal tar, petroleum pitch, asphalt binder, hydrocarbon residue, refined bitumen

4) Flash Point of Bitumen 80/100
The flash point of bitumen 80/100 is a crucial safety metric, indicating the temperature at which its vapors can ignite. ASTM D92 specifies a minimum flash point of 250°C.
SEO Snippet: The flash point of bitumen 80/100 is 250°C, ensuring safe handling during heating and asphalt mixing processes.
Section Summary: Flash point testing, using open or closed vessels, determines the ignition risk. The ignition point is slightly higher than the flash point, and self-ignition temperatures must be considered during storage and transport. Proper safety protocols are essential.
LSI Keywords: bitumen safety, flash point, ignition point, ASTM D92, petroleum hydrocarbon, asphalt heating, thermal safety
