Description of bitumen 160/220

Bitumen penetration grade 160/220 is a standard penetration grade bitumen usually used as a paving grade bitumen for roadworks and also used to manufacture hot-mix asphalt. Our penetration grade bitumen is a petroleum grade bitumen, manufactured from fractional/vacuum distillation of crude oil. The grades of our bitumen are specified by the penetration and softening point test. The term 160/220 are actually its penetration range at 25°C (from 160 to 220 mm/10). Our penetration grade bitumen have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature and viscosity relationship is important when determining the performance parameters such as adhesion, rheology, application temperatures and durability.

Uses of bitumen 160/220

Bitumen 160/220 is suitable for road construction and repairs. It is also used in the manufacture of hot mix asphalt for bases and wearing courses.
