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.Softening point and penetration
Penetration grade bitumen supplied by jey pasargad is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by jey pasargad is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 70/100 has penetration between 70~100 desi-millimeter and softening point between 43 ~ 51C. The penetration grade has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 70/100 has very strong viscosity compare to other grades.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.Application of bitumen penetration grade 70/100
jey pasargad penetration grade 70/100 is hard penetration grade bitumen using as paving grade bitumen with superior properties suitable for road construction and repair also for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.Guaranty/warranty of asphalt 70/100
jey pasargad guaranty the quality of bitumen 70/100 with arrangement of international inspector to check quality and quantity of the bitumen during the loading to vessel and controlling the production by QC by batch test report before shipping. We guaranty the quality to meet with ASTM/EN 12591.Specification of penetration bitumen
