Bitumen VG 40

Description

Bitumen VG 40 is a type of viscosity-graded bitumen commonly used in road construction and paving applications. The “VG” in VG 40 stands for “Viscosity Grade,” and the number 40 indicates the viscosity level of the bitumen at 60°C. VG 40 is particularly suitable for use in hotter climates due to its higher viscosity, making it less prone to softening under high temperatures.

Key Properties of Bitumen VG 40:
Viscosity: VG 40 bitumen has a higher viscosity compared to other grades like VG 10 or VG 30, providing better resistance to deformation under heavy traffic loads.
Penetration Value: The penetration value is lower, indicating that VG 40 is harder, which makes it more resistant to high temperatures and rutting.
Application: It is typically used in the construction of highways, airfields, and heavy-duty asphalt pavements, especially in regions with hot climates.
Temperature Susceptibility: VG 40 has a lower temperature susceptibility, meaning it performs better under varying temperature conditions, providing longer-lasting pavement in hot climates.
Performance: Due to its higher viscosity, VG 40 bitumen provides better load-bearing capacity and resistance to shear deformation, making it ideal for heavy traffic roads.

Bitumen VG 40 Applications:

1. Road Construction
High-Traffic Roads: Bitumen VG 40 is ideal for constructing roads with high traffic density, such as highways and expressways. Its higher viscosity makes it suitable for regions with heavy vehicular load and extreme weather conditions.
Pavement Layering: It is used in the top layers of road pavements where a higher resistance to deformation and higher temperature tolerance is required.
Hot Mix Asphalt (HMA): VG 40 is used in the preparation of hot mix asphalt, especially in areas with higher temperatures and where heavy traffic is expected.
2. Airfield Construction
Runways and Taxiways: Due to its high viscosity, VG 40 bitumen is used in the construction of airfield runways and taxiways, which require durable and heat-resistant materials to withstand the heavy loads of aircraft.
3. Industrial Applications
Waterproofing: VG 40 can be used in waterproofing applications due to its water-resistant properties.
Damp-Proofing: It is also used in damp-proofing of foundations and basements to prevent water ingress.
Adhesives: VG 40 bitumen is sometimes used in the production of industrial adhesives and sealants due to its strong bonding properties.
4. Bridges and Overpasses
Heavy Load Bearing: VG 40 is suitable for use in the construction of bridges and overpasses where a strong, durable, and weather-resistant material is necessary.
5. Railway Ballast
Railway Track Beds: It is used in the construction of railway track beds to provide stability and reduce maintenance by minimizing track deformation.
Bitumen VG 40 is specifically formulated for regions where higher viscosity is needed to handle the stress from heavy traffic loads and extreme temperatures, making it a preferred choice for critical infrastructure projects.

Asia bitumen Factory with more than 20 years of experience is one of the major suppliers and exporters of bitumen VG 40 and has the ability to sell its product as soon as possible with the best quality and reasonable price as well as proper packaging according to the type of bitumen Offer.

Bitumen VG 40 Packing:

Packing for this grade of Bitumen would be like other kinds of our Bitumen products too and packing would be 180 kg new steel drums.
