Bitumen VG30 (Viscosity Grade 30) is paving-grade bitumen that is used for road construction. This type of bitumen is suitable for use in moderately hot regions and medium to heavy traffic conditions. Dense bituminous macadam (DBM) and bituminous concrete (BC) mixes are perfect for this. VG30 is preferred over penetration-grade bitumen since it offers improved control over viscosity. It has a good bond with aggregates, good resistance to deformation, and good water stability. VG30 is a specification for bitumen widely used in highways, runways, and urban road projects and conforms to IS 73:2013 specifications.
Benefits:
1. Balanced viscosity ensures optimal performance under traffic stress.
2. Suitable for hot climates and moderately loaded roads.
3. Enhances pavement durability with good adhesion and flexibility.
4. Reduces susceptibility to rutting and thermal cracking.
5. The quality of the product is as per IS 73:2013 specifications.
