Bitumen 30 40, Loss On Heating(wt) % 0.2 Max Application: Industrial

Asphalt pavements are designed to be produced with Penetration Bitumen 30 40 specifications. Penetration Bitumen Grade 30-40 is also used for road construction and repairs as well as the production of asphalt pavements. The main application of this bitumen grade is the manufacture of hot mix asphalt for the preparation of bases and wearing courses.

Hot mix asphalt for bases and wearing courses usually contain Bitumen Penetration Grade 30/40. Bitumen for penetration grade is derived from fractional / vacuum distillation of crude oil and is manufactured by Vira Petroleum.

By testing the penetration and softening points of bitumens, penetration grade bitumens can be distinguished. A thermoplastic property makes penetration grade bitumens soft at high temperatures and hard at low temperatures. When it comes to bitumen performance parameters such as adhesion, rheology, durability, and application temperatures, the unique temperature-viscosity relationship is essential.

Temperature influences the Bitumen mode. Temperature versus stiffness of bitumen varies according to crude oil type and refinement process. It is suitable for road construction and repair since it is a penetration grade bitumen of semi-hard hardness.
