Manufacturer of straight asphalt bitumen grade 160/220

General description of bitumen 160/220

ADTM bitumen penetration grade 160/220 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.

Softening point and penetration of bitumen 160/220

Penetration grade bitumen supplied by ATDM is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by ATDM is produced from remain of crude oil after cracking and removing hydrocarbon. It has penetration between 160~220 desi-millimeter and softening point between 35~ 43C. The penetration grade bitumen 160/220 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade has very strong viscosity compare to other grades.

Guaranty/warranty of bitumen

ATDM guaranty the quality of bitumen 160/220 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. ATDM guaranty the quality to meet with ASTM/EN 12591.
