Bitumen 70/100
General description of bitumen 70/100
Bitumen 70/100 is soft 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.
Paving Grade Bitumen 70/100 is a high quality bitumen produced in government refineries with the most modern industrial processes and using appropriate crude oils. It has an optimum viscosity in the range of temperatures for mixing and laying that guarantees easy workability of the products, even for high stress conditions. The product meets the ASTM,GB and European standard EN 12591 and achieves the maximum level of hardening resistance.
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 70/100 has penetration between 70~100 desi-millimeter and softening point between 43 ~ 51C. 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 the bitumen has very strong viscosity compare to other grades.
Guaranty/warranty of asphalt 70/100
ATDM guaranty the quality of bitumen 70/100 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.
