Description
Viscosity Grade Bitumen is mostly used as a Paving Grade and is suitable for Road Construction and Asphalt pavement production with premier attributes. Viscosity Grade Bitumen is usually used in the production of Hot Mix Asphalt. Viscosity Grade Bitumen has a thermoplastic feature that causes the material to Soften at High temperatures and to Harden at Lower temperatures. This temperature viscosity relevance is significant when specifying the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen. In the Viscosity Grade Bitumen Specifications, the most important emphasis is on the Bitumen ductility.

Viscosity Grade Bitumen (VGB) is a type of bitumen that is graded based on its viscosity properties. It is commonly used in road construction and other applications that require a high degree of durability and resistance to deformation. The application of VGB typically involves the following:
- Heating: VGB is heated to a liquid state before it can be applied to a surface. The heating process can be done using specialized equipment such as a hot oil heater or a direct-fired heater.
- Mixing: VGB is mixed with aggregate materials to form asphalt concrete, which is used as a surface layer in road construction. The mixing process can be done using a variety of equipment such as a drum mixer, batch plant, or pugmill mixer.
- Application: VGB is applied to a surface using a variety of methods such as spraying, spreading, or rolling. The application method used will depend on the specific requirements of the project and the equipment available.
- Compaction: After VGB is applied, it is compacted using specialized equipment such as a roller or vibratory compactor. The compaction process helps to ensure that the VGB adheres well to the surface and provides a durable and long-lasting surface.
Overall, the application of VGB is an important step in the construction and maintenance of roads and other paved surfaces. By providing a durable and long-lasting surface, VGB helps to ensure the safety and reliability of our transportation infrastructure.
