BITUMEN VG40 ( High Viscosity )

es Bitumen is categorized according to Viscosity (degree of fluidity) grading. The stiffness of Bitumen increases with the increase in grade. Viscosity tests are conducted at two temperatures, 60°C and 135°C, which represent the temperature of the road surface during summer and mixing temperature respectively, in the Viscosity Grade. The penetration at 25°C, which is the annual average pavement temperature, is also considered in the Specifications. Advantage of Viscosity Grade Bitumen Viscosity Grade Bitumen bitumen is suitable for a wide range of temperatures; 25 ◦C for fatigue cracking and 135 ◦C for construction, also temperature susceptibility can be determined. According to IS, it has only 7 tests while penetration has 14 tests. Fewer tests save time and money. The use of VG Bitumen results in longer-lasting pavement due to its optimal mixing and compaction temperature, which improves pavement performance over time. Any two samples of VG bitumen will exhibit similar rutting performance in hot summer, unlike the penetration grade. The specified minimum kinematic viscosity value at 135 ◦C helps minimize the chance of tender mixes during construction. VG bitumen is a type of bitumen that is specifically designed for areas with high traffic loads. It is a durable and long-lasting material that is ideal for use in high-traffic areas such as highways, airports, and industrial zones. Application of Viscosity Grade Bitumen (Asphalt) Viscosity Grade Bitumen, also known as Asphalt, is a standard grade of Bitumen that is commonly used for road construction and for producing asphalt pavements with superior properties. This type of Bitumen is primarily used in the manufacturing of hot mix asphalt for bases and wearing courses. It possesses unique characteristics and qualities that are different from other agents and can achieve very flexible and tenacious connections with other materials due to the viscoelastic response of Bitumen, which depends on how fast charges are applied. Sebco supplies petroleum-grade Bitumen that is manufactured from fractional/vacuum distillation of crude oil. The practical application and behavior of this grade of Bitumen vary according to its temperature. The Bitumen supplied by Sebco is produced from the vacuum residue (short residue) feedstock. Viscosity Grade bitumens are specified by the methods described in ASTM Standard D3381–09 and AASHTO M226-80 (2008). Viscosity Graded specifications cover bitumen (asphalt) graded by viscosity at 60°C (140°F). **** VG-10 Bitumen: Recommended for cold weather road construction. Ideal for spraying and producing bitumen emulsion. VG-20 Bitumen: This material is utilized in regions with low temperatures to construct roads. VG-30 Bitumen: Maximizes asphalt performance in hot regions; a more reliable choice than bitumen 60/70. VG-40 Bitumen: High-traffic areas such as intersections, near toll booths, and heavy vehicle parking lots require a stronger and more durable pavement. To achieve this, VG40 bitumen is used instead of the traditional bitumen 50/35. VG40 has a higher viscosity, which allows for the production of harder bitumen mixtures that can resist problems associated with higher temperatures and heavy traffic loads, such as drift.
