The Price of Viscosity Grades Bitumen + Purchase and Sale of Viscosity Grades Bitumen Wholesale
The bitumen viscosity grades have played a dominant role in the bitumen market of India in recent years
The increasing demand for bitumen products has grown tremendously over the past decade
bitumen grades in india
More than 60% of the national road projects are VG-10, VG-40, and other grades of VG-30 and above
VG grade is known as the preferred type of bitumen for road construction by the Government of India
In 1991, bitumen manufacturers started producing and supplying viscosity classes of bitumen after the Bureau of Indian Standards adopted a new class of bitumen grading method called viscosity grading to better control bitumen mix performance
Compared to the widely used entry method for bitumen grades, the viscosity grade system is very focused on the field performance of bitumen in India
In this grading method of bitumen viscosity is measured at 60°C and 135°C, to identify the properties of bitumen at low and high temperatures According to VG Bitumen’s FAQ published by India’s largest oil refiner IOCL, “As measured viscosity values at 60°C correlate well with rutting behavior and viscosity values at 135°C give adequate idea, Packaging will perform well for mixing and compression temperatures”
So sticky bitumen pavements are durable, resist rust in hot weather and fatigue cracks in cold winters The use of viscosity class of bitumen follows the Indian standard IS-73-2006 for bitumen specification packaging
This standard was developed using the American standard ASTM D 3381, which classifies bitumen into four categories: AC bitumen, AC-10, AC-20, AC-30, and AC-40 In hot climates like India, AC rating system good performance with heavy rainfall in Southeast USA She did it
The Indian Standard of IS-73-2006 introduces four VG grades including VG-10 bitumen, VG-20 bitumen, VG-30 bitumen and VG-40 bitumen
bitumen grades and uses
Application of viscosity grades of bitumen: Each grade of VG bitumen has a variety of properties that make it suitable for a specific application
The higher the number, the harder the bitumen in the viscosity grading system
VG-30 is the most widely used bituminous grade in India
This grade is used primarily in the construction of heavy-traffic and extra-weight bitumen slabs
VG-30 is also used in hot climates due to its high temperature resistance
This grade of bitumen is the preferred category for sellers and buyers of VG bitumen due to its proven high performance in Indian road projects Learn more about VG 30 bitumen
VG-40 bitumen is used where high pressure is generated in high traffic areas such as intersections, near toll gates and truck parking This bitumen is more suitable for improving exhaust resistance associated with higher temperatures and heavy traffic loads due to its high viscosity VG Bitumen Price and Quality High quality vacuum floors (raw material for bitumen production) are used to produce viscosity class bitumen
As a result, the final product is always of good quality
Supply and demand in VG Bitumen, India With the introduction of viscosity grade bitumen in India, many refineries have shifted to VG bitumen production to meet the demand of Indian road projects
For example, state-owned Indian Oil Corp
Ltd
(IOC) in 2016 increased the capacity of the Barauni refinery to produce 150,000 TPI of VG-30, VG-40 and VG-10
Refineries in India can now produce various grades of VG coke, but in recent years consumption of these grades has exceeded production
This means that India will depend on VG bitumen imports due to rising infrastructure spending and expansion of road network across India
The market for Indian bitumen is estimated at about 5 million tons with the target of improving the road network
In September 2020, India’s bitumen consumption was 444,000 tons
India has the second largest road network in the world after the US with over 47,000 km of road infrastructure
The next 90% of India’s bitumen demand comes from government-owned refineries and the remaining 10% is mainly imported from the UAE and Iran
According to import data for 2016, between January 1 and November 26, VG bitumen imports from India stood at $44 million
Iran and the United Arab Emirates were the main suppliers of VG cola to India after Malaysia and Singapore during this period
Entry Grade Bitumen: Ideal bitumen for road construction A common type of access grade bitumen for road construction
This type of bitumen is known for its durability and resistance to temperature changes
Therefore, many refineries around the world have special plants for producing entry grades
bitumen grade 60/70 indicates
Entry grade bitumen is actually a broad range of bitumen with at least 5 subgrades which are bitumen 30/40, 40/50, 50/70, 60/70, 80/100 and 100/120
Each subgrade of bitumen entered has a number indicating the hardness level
In refineries, experts test bitumen by a penetration method that indicates the hardness by drilling a standard needle into the bitumen and measuring the rate of penetration Bitumen 30/40 samples have a penetration of 30-40 mm
Bitumen 60/70: The most widely used grade of permeable bitumen The bitumen entered is an intermediate type of bitumen in terms of grade 60/70 hardness, neither too hard nor too soft
Thus, the penetrating bitumen of this class resists temperature changes from -22 to +76
Therefore, it is the perfect choice for road engineers in different regions, especially Asia and Southeast Africa
Properties of entry grade bitumen 60/70: Each grade of bitumen has different properties depending on the source (crude oil) and processing method
All bituminous producers and suppliers are therefore responsible for testing the bitumen after production and providing the specification table to the buyer
Bitumen 60/70 is no exception
Once this grade of bitumen is made, the researcher sends the sample to a laboratory where it undergoes various tests including penetration, viscosity, flash point, softening point, ductility and specific gravity The results of all these tests are 60/70 essential for assessing bitumen quality, but the penetration level and softening point are more important Bitumen 60/70 has a penetration of 60-70 mm and a softening point of 46°C
