Description of bitumen 70/100
Bitumen penetration grade 70/100 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 70/100 are actually its penetration range at 25°C (from 70 to 100 mm/10). Our penetration grade bitumens 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 70/100
Bitumen 70/100 is suitable for road construction and repairs. It is also used in the manufacture of hot mix asphalt for bases and wearing courses.
