What is Bitumen 80/100

Bitumen 80/100 is a specific type of bitumen, commonly known as penetration grade bitumen. The numerical nomenclature refers to the penetration value, which measures the hardness or consistency of the bitumen. Bitumen 80/100 penetration values vary from 80 to 100.So this type of Bitumen Grade is soft and ideal for chilly areas. Bitumen 80/100 has a density of 980-1050 kg/m³ at room temperature (0.98-1.05 g/cm³).

Production Process of Bitumen 80/100

Bitumen 80/100 production consists of numerous phases, beginning with crude oil extraction and ending with bitumen refinement and modification to obtain the needed qualities. Here’s a summary of the production process:

Bitumen 80/100 goes through an important production stage called air blowing.
When the bitumen is blasted, hot air surges up through it. During this process, bitumen is oxidized and polymerized, modifying its molecular structure and improving physical qualities like as hardness and temperature sensitivity.

Overall, bitumen 80/100 may be manufactured depending on ASTM D 946 and AASHTO M 20 criteria.

Where is Bitumen Penetration Grade 80/100 Used?

Road building: Bitumen 80/100 is mostly used in road building. It acts as a binder in asphalt mixes, adding durability and flexibility to the road surface.

Roofing and Waterproofing: Bitumen 80/100’s waterproofing characteristics make it an appropriate roofing material. It is widely utilized in the fabrication of roofing felt and membranes.

In rehabilitation projects, Bitumen 80/100 is used to improve the durability and strength of existing pavements, hence prolonging their service life.
