What is Bitumen VG10 ?
Bitumen VG10 is a type of viscosity-grade bitumen, a hydrocarbon product made from crude oil fractional distillation. The term “VG10” refers to the viscosity measure, which indicates that this type of bitumen will behave exceptionally well in cold climates, in contrast to other types of bitumen that may not exhibit the same amount of flexibility at low temperatures and would eventually develop cracks or blemishes on the road surface.
This product is thermoplastic, so it hardens in low temperatures and becomes soft when exposed to heat.
This much adaptability ensures that the performance is optimum over a wide range of temperatures; thus, this is the favored variety for road construction in areas when the weather tends to get cold.
Essentially, Bitumen VG 10 is a strong and versatile pavement road construction material, formulated to provide durability and resistance-particularly to adverse climatic conditions.
Uses of Bitumen VG10
Applications Bitumen VG-10 is mostly utilized in spraying usages such as surface dressing and also paving in cold weather as a replacement for old 80/100 Penetration grade.
VG10 bitumen is used in asphalt production, especially in hot asphalt for surfacing. In terms of appearance, VG-10 bitumen is soft and somewhat fluid in hot weather around 40 degrees Celsius.
One of the uses of VG-10 bitumen is gluing isogram or covering the first layer of asphalt as an adhesive on the desired surface. Also, mostly VG10 bitumen is used to make emulsion bitumen and modified bitumen products.
Difference Between Bitumen VG10 & VG20
The main difference between Bitumen VG10 and VG20 is the viscosity and application of each. VG10 has a lower viscosity, hence it is applied in moderate and cold climates for spray sealing, thin layers of asphalt, and hot mix. VG20 has a higher viscosity, hence it is preferred in cold climates and high altitudes as it is more resistant to cracking and bad weather conditions. VG20 is also used extensively in wearing and base courses, providing greater durability and adhesion compared to VG10, especially in regions with low temperatures and temperature fluctuations.
Packing
The packing configurations of VG10 bitumen are different means to satisfy different transportation needs. For low volume, VG10 is packed in 180 kg new steel drums, and 110 drums are packed in a 20 ft container.
The bitumen may also be packed in 375 kg Bitubags, with 24 metric tons (MT) of them loading in a 20 ft container.
For large-scale shipments, massive quantities are directly loaded into ships, with capacities of 2,000 to 20,000 MT in a bitumen carrier. VG10 is also shipped in bulk using Flexi Bags, in which a single bag has the capacity of 20 MT, or truck tankers, in which each tanker can carry 25 MT of bitumen.
Such alternatives ensure flexibility and efficacy in transportation of VG10 bitumen to match the specialized demands of delivery.
