What is VG in bitumen?

VG10 bitumen is the softest grade of viscosity bitumen. This type of bitumen is widely used for spraying applications and surface coating. VG 10 bitumen means that your bitumen is also suitable for paving roads in a very cold climate instead of the old 80/100 penetration grade.

What is VG 40 grade bitumen?

VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots instead of 30/40 penetration grade. Because of higher viscosity, stiffer Bitumen mixes can be produced to amend resistance to shoving and other problems related to higher temperature and heavy traffic loads.

What is VG in VG 30?

VG-30 BITUMEN: VG-30 is primarily used to construct extra heavy duty Bitumen pavements that need to endure substantial traffic loads. It can be used in lieu of 60/70 Penetration grade.

What is viscosity grade of bitumen?

Viscosity grades Bitumen are categorized according to Viscosity (degree of Fluidity) grading. The higher the grade, the stiffer the Bitumen. In Viscosity Grade, Viscosity tests are conducted at 60 deg. C and 135 deg. C, which represents the temperature of road surface during summer and mixing temperature respectively.

What is the meaning of 60 70 bitumen?

A grade of 60/70 bitumen means the penetration value is in the range 60 to 70 at standard test conditions which usually used as a Paving Grade. Bitumen 60/70 is applicable for the production of asphalt pavements with superior properties and for construction and maintenance of roads.

Viscosity Grades Of Bitumen and there suitability #VG10 #VG20 #VG30 #VG40

What is the meaning of 80 100 bitumen?

Bitumen grade 80/100 meaning

Bitumen of grade 80/100 means that in the bitumen penetration test, when the needle sinks 8 to 10 mm in the bitumen, we find out that the penetration value is between 8 and 10 mm and this type of bitumen is 80/100 bitumen.

What is BM and BC road?

DBM (Dense Bituminous Macadam) & BC (Bituminous Concrete) are the top most layers of an Bituminous Top Roads, whose thickness is determined my MSA & CBR. CBR- California Bearing Ratio is a method of determining the mechanical strength & Load bearing capacity of soil.

Why VG 30 bitumen is used?

VG-30 BITUMEN: VG-30 is primarily used to construct extra heavy duty Bitumen pavements that need to endure substantial traffic loads. It can be used in lieu of 60/70 Penetration grade.

What does VG 40 mean?

VG-40 is used in highly stressed areas such as intersections, near toll booths and truck parking lots instead of 30/40 penetration grade. Because of higher viscosity, stiffer Bitumen mixes can be produced to amend resistance to shoving and other problems related to higher temperature and heavy traffic loads.

What is s 35 grade bitumen?

Bitumen Penetration Grade 35/50 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.

Is code for bitumen VG 30?

Bitumen Vg30 Import Data under HS Code 27132000 with Price.

What is viscosity grade?

Viscosity is determined by the fluid's resistance to flow. The viscosity grade of an engine oil provides information on the oil's resistance to flow in your vehicle's engine. An engine oil with a low viscosity grade will be more fluid and will flow easily.

What is softening point of bitumen?

The softening point of various bitumen grades generally lies between 35°C to 70°C. Softening point of bitumen to be used for road construction at a place where the maximum temperature is 40°C should be greater than the 40°C.

What do you understand by the term 30 40 bitumen?

Description of Bitumen 30/40. Penetration Bitumen Grade 30-40 is Semi-Hard penetration grade bitumen using as Paving Grade Bitumen suitable for road construction and repair also for the production of Asphalt pavements with below Penetration Bitumen 30/40 Specifications.

What is mc1 bitumen?

description: Cut back petroleum asphalt of the medium curing type for use in the construction and treatment of roads.

How do you measure viscosity of bitumen?

Saybolt Furol viscosity test is used to determine viscosity of liquid bitumens. In this test, time in seconds is noted for 60 ml of the liquid bitumen at specified temperature to flow through an orifice of a specific size. The higher the viscosity of the bitumen more time will be required for a quantity to flow out.

What is the density of bitumen?

The density of bitumen is 1.01-1.05 g/cm 3 in the temperature range of 25°C to 85°C [63] .

What is the units of viscosity?

The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.

What is ductility test of bitumen?

property of bitumen which allows it to undergo deformation or elongation is called ductility of bitumen. The ductility of bitumen is measured by the distance in Cm (centimeter), to which the bitumen sample will elongate before breaking when it is pulled by standard specimen at specified speed and temperature.

How do you calculate bitumen road?

Which grade of bitumen is used in hot climate?

A grade of 40/50 bitumen means the penetration value is in the range 40 to 50 at standard test conditions. In hot climates, a lower penetration grade is preferred.

What is DBM layer?

Engineering. Dense Bituminous Macadam (DBM) is a binder course used for roads with more number of heavy commercial vehicles and a close-graded premix material having a voids content of 5-10 per cent.

What is DBM laying?

Dense Bituminous Macadam (DBM) Preparation and Laying Methodology. Description. The DBM materials shall be laid by a self-propelled sensor paver finisher equipped with a hopper, delivery augers and capable of spreading, tamping and finishing the mix to specified grade, lines and cross-section.

What is DBM and BC?

DBM (Dense Bituminous Macadam) & BC (Bituminous Concrete) are the top most layers of an Bituminous Top Roads, whose thickness is determined my MSA & CBR. CBR- California Bearing Ratio is a method of determining the mechanical strength & Load bearing capacity of soil.
