What do you understand by 80 100 between?

Properties of Bitumen 80/100 Penetration grade bitumen 80/100 has penetration between 80~100 desi-millimeter and the softening point between 42 ~ 50C. The penetration grade bitumen 80/100 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled.

What do you mean by penetration grade of bitumen?

The penetration grade bitumen is refinery bitumen that is manufactured at different viscosities. The penetration test is carried out to characterize the bitumen, based on the hardness. Thus, it has the name penetration bitumen. The penetration bitumen grades range from 15 to 450 for road bitumen.

What is the penetration value of bitumen test?

Penetration test is a commonly adopted test on bitumen to grade the material in terms of its hardness. A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100. Grading of bitumen helps to assess its suitability in different climatic conditions and types of construction.

What is penetration grade?

The penetration grading system was developed in the early 1900s to characterize the consistency of semi-solid asphalts. Penetration grading quantifies the following asphalt concrete characteristics: Penetration depth of a 100 g needle 25° C (77° F)

What does an 80 100 grade bitumen indicate Mcq?

The unit of penetration is 1/10 mm. Thus 80/10 grade bitumen means 8 – 10 mm penetration. 30/40 and 80/100 grade bitumen are more commonly used, depending upon bitumen construction type and climate conditions.

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.

What are the grades of bitumen?

Application of viscosity grade bitumen

What does 80 100 pen asphalt cement mean?

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.

What is a 80 grade?

Letter grade Percentage Grade definition A+ 90-100 Excellent A 85-89 Very good A– 80-84 Very good B+ 75-79 Good B.

Is an 80 good on a test?

A – is the highest grade you can receive on an assignment, and it’s between 90\% and 100\% B – is still a pretty good grade! This is an above-average score, between 80\% and 89\% C – this is a grade that rests right in the middle.

What is a 81\% as a grade?

What is a 80/100 grade bitumen?

A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100. Penetration test is a commonly adopted test on bitumen to grade the material in terms of its hardness. Grading of bitumen helps to assess its suitability in different climatic conditions and types of construction.

What is the recommended penetration value of bitumen?

Recommended Penetration Value of Bitumen. Penetration test is a commonly adopted test on bitumen to grade the material in terms of its hardness. A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100.

What is Penpen test for bitumen?

Penetration test is a commonly adopted test on bitumen to grade the material in terms of its hardness. A 80/100 grade bitumen indicates that its penetration value lies between 80 & 100. Grading of bitumen helps to assess its suitability in different climatic conditions and types of construction.

Which grade of bitumen is manufactured from Assam petroleum?

Other grades of bitumen can be 30/40 (3-4 mm penetration value on penetration test), 60/70 (6–7 mm penetration). If grade of bitumen is A-30 then bitumen is manufactured from Assam petroleum. If grade is S-30 then it is other than Assam petroleum.
