grade 50/70

Description of bitumen 50/70

Bitumen penetration grade 50/70 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 50/70 are actually its penetration range at 25°C (from 50 to 70 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 50/70

Bitumen 50/70 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 50/70

Bitumen 50/70 is suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the road at tropical regions

Softening point and penetration

Penetration grade bitumen supplied by Gold Bitumen is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by Gold Bitumen is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 50/70 has penetration between 50~70 desi-millimeter and softening point between 52 ~ 58C. 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 50/70 has very strong viscosity compare to other grades.

Guaranty/warranty of bitumen

Gold Bitumen guaranty the quality of bitumen 50/70 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.
