What is meant by grade of bitumen?
The difference between 80/100 and 60/70 penetration grade is the penetration range. Bitumen 60/70 has lower penetration which means it is harder than bitumen 80/100. To the contrary of bitumen 80/100, Bitumen 60/70 is suitable to be used in hot climates and it shows more durability exposing to heavy traffic loads.
What does it mean by bituminous grade 80 100?
Bitumen Penetration Grade 80/100 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.
Which grade of bitumen hardness is higher?
The greater the penetration value, the softer the bitumen become. The ASTM standard D 946 gives 5 penetration grades for the bitumen binders. They are: Hardest Bitumen Grade 40 –50.
What is VG-40 grade bitumen?
VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots in lieu of old 30/40 Penetration grade. Due to its higher viscosity, stiffer Bitumen mixes can be produced to improve resistance to shoving and other problem associated with higher temperature and heavy traffic loads.
Is 60 an A or B?

| Scale | Letter Grade |
|---|---|
| 90–100 | Excellent (AA or S) |
| 80–89 | A |
| 70–79 | B |
| 60–69 | C |
What are the three types of bitumen?
Three types of bituminous emulsions are available, which are Rapid setting (RS), Medium setting (MS), and Slow setting (SC). Bitumen emulsions are ideal binders for hill road construction.
What is a 80 100 grade?
Description of Bitumen 80/100 Bitumen Penetration Grade 80/100 is a standard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties.
What do you mean by 60 80 grade bitumen?
Paving Asphalt 60/80 M is a penetration graded asphalt product derived from specially selected crude oils via carefully controlled refining processes.
Which grade of bitumen is best?
Bitumen VG30 is the most widely used type of bitumen in road construction, insulation, building construction industries, and also in the production of cutback bitumen. It’s better to know that this vg30 bitumen can be used instead of 60/70 penetration bitumen grade. VG 30 bitumen is a popular grade of bitumen in India.
What is the softening point of bitumen 60 to 70 grade?
between 49 to 56 °C
Some of these items are more important for suppliers of bitumen 60/60 and their customers. These are softening point and flashpoint. According to ASTM D36 method, the softening point of bitumen 60/70 is between 49 to 56 °C and the flash point of bitumen 60/70 is 250 °C.
What is a 75% grade?
What is a 75 percent in GPA?
| Letter Grade | % | GPA Number |
|---|---|---|
| A | 80-89 | 8 |
| B+ | 75-79 | 7 |
| B | 70-74 | 6 |
| B- | 65-69 | 5 |
Which is the best penetration grade for bitumen?
1 penetration unit = 0.1mm. The greater the penetration value, the softer the bitumen become. The ASTM standard D 946 gives 5 penetration grades for the bitumen binders. They are: The penetration grading system is 100 years old bitumen grading method. In India, before 2006, the most widely used grade of bitumen was 60 to 70.
What are the grades for bitumen binders in India?
The ASTM standard D 946 gives 5 penetration grades for the bitumen binders. They are: The penetration grading system is 100 years old bitumen grading method. In India, before 2006, the most widely used grade of bitumen was 60 to 70.
What kind of bitumen is used to make bitumen?
Penetration Grade Bitumen supplied by BITUMENSHOP is petroleum grade bitumen, manufactured from VB distillation of crude oil. Penetration Grade bitumens are specified by the penetration and softening point test. Designation is by penetration range only.
What are the grades for cold service bitumen?
The grades with lower viscosity i.e. AC-2.5 and AC-5 were used for cold service temperatures; areas like Canada. In Northern tier states, AC-10 was used. Mostly in the US, AC-2- was used. Only five grades excluding AC-30 was initially determined. These have a mean viscosity that will double from grade to grade.
