General description of bitumen 40/50

Semi soft grade bitumen penetration 40/50 a penetration bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. The Bitumen 40/50 is also used to manufacture bitumen mix, hot asphalt mix for bases and wearing courses, cutbacks, emulsions and modified bitumen.

Softening point and penetration

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. Penetration grade bitumen 40/50 has penetration between 40~50 desi-millimeter and softening point between 52 ~ 60C. 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  has very strong viscosity compare to other grades.

Guaranty/warranty

ATDM guaranty the quality of bitumen 40/50 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.ensuring customer confidence  and satisfaction.
