Viscosity Bitumen Characterized by its viscosity grade, it's suitable for high-temperature applications, ensuring stability and flexibility.
Bitumen Viscosity Grade
Standard Viscosity Grade Bitumen (AC-Grades), in which the Viscosity of the standard bitumen (asphalt) is measured at 60 C (140 F). RTFOT Viscosity Grade Bitumen (AR-Grades), in which the Viscosity of bitumen (asphalt) is measured at 60 C (140 F) after the roll on thin film oven test. Viscosity grade bitumen have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of bitumen. In the Viscosity Graded Bitumen specifications further special emphasizes is placed on the Bitumen ductility.
To grade the bitumen-based on viscosity BIS revised IS-73-1992 specifications (Viscosity at 60 C) and as such there are four grades VG-10, VG-20, VG-30 & VG-40. A few qualification tests like specific gravity, water content, ductility, loss on heating & fares breaking point were removed from IS:73-1992 as these tests do not have any relationship with the performance of the product. Viscosity Grade Bitumen is widely used in spraying applications such as surface-dressing and paving in very cold climates. It is also used to manufacture bitumen emulsion and modified bitumen products.
VG-20 bitumen is a grade of viscosity bitumen used in cold climatic and high altitude regions. This grade of bitumen is suitable for road construction in regions with 30 to 37 C average temperature. In North India, vg20 is used for road construction in hot mix asphalt. The standard penetration value of bitumen viscosity grade VG-20 is 60 mm at 25 C. The absolute viscosity of VG-20 bitumen is 1600 to 2400 poise at 60 C.
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. The air temperature that matches VG10 bitumen ranges from -10 �¢?�¦C to 25 �¢?�¦C. Due to the high temperatures in hot climatic zones, the application of VG10 cannot provide desirable rutting resistance. This type of bitumen is also used to manufacture bitumen emulsions and modified bitumen products especially in India. As a viscosity grade bitumen, VG10 has a better performance incold weather.

VG40 bitumen is used in areas in which high pressure comes from heavy traffic loads, such as intersections, near tolls booths, and truck parking lots. Due to the high viscosity of this bitumen, it is more appropriate for improving resistance to shoving and other problems associated with higher temperatures and heavy traffic loads. It's long time that industries use vg-40 instead of the penetration grade bitumen 40/50.

Bitumen, often referred to as asphalt, is a viscous, black, and sticky substance. It is a semi-solid form of petroleum and is primarily used as a binder in road construction. When mixed with aggregates, it forms asphalt concrete, the material commonly used for paving roads. Primary Characteristics: Appearance: Thick, black to dark brown substance. Temperature Sensitivity: Becomes liquid when heated and returns to a semi-solid state upon cooling. Water Resistance: Acts as a waterproofing agent, making it ideal for various sealing applications. Adhesion: Excellent adhesive properties, allowing it to bind aggregates together effectively. Grades & Types: Bitumen comes in various grades, primarily determined by its viscosity and penetration value. Common types include: Paving Grade Bitumen: Used in road construction. Oxidized Bitumen: Produced by air blowing and has stiffer properties. Cutback Bitumen: Bitumen diluted with solvents to reduce viscosity for specific applications. Modified Bitumen: Bitumen altered with polymers to enhance its properties. Applications: Road Construction: Mainly used as a binder mixed with aggregates to pave roads. Roofing: Used as a waterproofing agent in roofing felts. Dams & Reservoirs: Acts as a waterproofing membrane. Soundproofing: Used in soundproofing materials due to its insulating properties. Advantages: Durability: Offers a long-lasting paving solution, able to withstand various weather conditions. Cost-effective: Provides a reliable and economical material for large-scale infrastructure projects. Recyclable: Old bituminous roads can be reprocessed to produce new roads.
