The term bitumen refers to a substance produced through the distillation of crude oil. Bitumen is known for its waterproofing and adhesive properties and is commonly used in the construction industry, notably for roads and highways. Production occurs through distillation, which removes lighter crude oil components like gasoline and diesel, leaving the heavier bitumen behind.
How is Bitumen Made?
Bitumen is a by-product of crude oil. It is commonly produced through a refining process in which crude oil is reduced. It removes lighter crude oil components and leaves behind the heavier bitumen. This product has many industrial applications. It is used in the construction of roads, where it is known as asphalt, and in roofing.
What is difference between Asphalt and Bitumen?
Bitumenis a residue of crude oil distillation occurs naturally. It is a semisolid hydrocarbon which is heavy in mass.
Asphalt is produced in the plant by mixing of fine sand, coarse sand, bitumen, gravel, and slag.
VG 30 or 60/70?
VG30 bitumen seems just like penetration grade 60/70; however, its physical properties, viscosity range, and performance is completely different.
In many applications, particularly road construction, VG30 bitumen is proven to work more efficiently than pen grade bitumen 60/70 at various temperatures. VG30 bitumen can be recognized from bitumen penetration grade 60/70, only with reference to standardized test results..
