General description of bitumen 90/130
ADTM bitumen penetration grade 90/130 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 the bitumen
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 has penetration between 90~130 desi-millimeter and softening point between 43~ 47C. The penetration grade bitumen 90/130 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 90/130 has very strong viscosity compare to other grades.
Guaranty|warranty
ATDM guaranty the quality 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.

What is Bitumen 90/130 used for?
Bitumen 90/130 is a moderately soft penetration grade used in asphalt surface layers, seal coats, and tack coats, offering good adhesion and flexibility.
How does Bitumen 90/130 compare to grades like 70/100 or 160/220?
Bitumen 90/130 is softer than 70/100 but harder than 160/220, making it suitable for climates with temperate ranges and mixed traffic demands.
What is the softening point of Bitumen 90/130?
The softening point typically ranges from 44 °C to 52 °C, striking a balance between heat resistance and ductility.
