Manufacturer of straight asphalt bitumen grade 30/40
General description of bitumen 30/40
High performance bitumen penetration grade 30/40 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 bitumen 30/40 has penetration between 30~40 desi-millimeter and softening point between 55 ~ 63C. 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 30/40 has very strong viscosity compare to other grades.
Guaranty|warranty
ATDM guaranty the quality of bitumen 30/40 with arrangement of international inspector to check quality and quantity of the Oxidized Asphalt 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.
