BITUMEN
Bitumen 60-70
bitumen penetration grade is semi 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. It also mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Bitumen 60-70 is mostly used bitumen grade and basic material for all other bituminous products. Temperature vs stiffness relationship of bitumen is dependent on type of crude oil and its refining method. It used as a paving grade bitumen which is suitable for road construction and repair. It also used for production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in manufacturing of hot mix asphalt for bases and wearing courses. It`s one of most used bitumen grades. Globally Bitumen`s Penetration Bitumen is pure petroleum product. It manufactured from vacuum bottom by passing hot air. Furthermore, penetration between 60~70 desi-millimeter and softening point between 48 ~ 52C. It has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 60-70 has very strong viscosity compare to other grades.
Bitumen ages
Aging refers to changes at intervals virtues of bitumen 60/70 over time. These changes unit of measure visible as cracks or crumbling areas. Once hydrocarbon is exposed to 0.5 conditions. Bitumen 60/70 molecules react with gas, that amendment of the structure and composition of the organic compound. Mixing with gas, calledoxidation, causes it become brittle, arduous and to vary color from dark brown or black to gray. This ageing happens further oftentimes in hotter condition. Also in heat seasons, inflicting older pavements to crack further just. Condition could in addition occur wherever surface films of hydrocarbon unit of measure skinny, or if there has been inadequate compaction throughout construction.

Guaranty of Bitumen 60-70
Globally Bitumen guaranty the quality of Penetration Grade 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. Our guaranty the quality to meet with ASTM/EN 12591. Our products rigorously conform to specifications of ASTM, AASHTO, EN and other international. Specially contains developed specifications and standards. Also we deploy external Quality Assurance Services from internationally renowned third party inspection companies such as SGS, Geochem, Bureau Veritas, Saybolt, Intertech and many others, to ensure and assure TDS of products delivered under our scope of delivery.
General Description of Bitumen 50/70
PUBLTD bitumen penetration grade 50/70 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 50/70
Penetration grade bitumen supplied by PUBLTD is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by PUBLTD is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 50/70 has penetration between 50~70 desi- millimeter and softening point between 52 ~ 58C. The penetration grade bitumen 50/70 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 50/70 has very strong viscosity compare to other grades.
Guaranty/warranty of bitumen 50/70
