About Bitumen 60-70:
Penetration Grade Bitumen ( like Bitumen 60-70) is classified using penetration property. It is a kind of bitumen, which is provided during the process of oxidation of vacuum bottom (the bitumen Definition: production feed-stock that derives from distillation tower residue in vacuum oil refineries) at bitumen production units in a manner that its penetration point (kind of test to indicate the hardness of bitumen) becomes between 60 70.
This system developed in 1900s to characterize the register of semi-solid asphalts. Penetration grading quantifies the following asphalt concrete specs:
Penetration depth of a 100 g needle 25° C.
Flash point temperature
Ductility at 25°C.
Solubility in trichloroethylene
Thin film oven test(effects of short-term aging that occurs during mixing with hot aggregate)
Ductility at 25° C.
Less viscous asphalt = deeper needle will penetrate.
Also penetration depth is empirically correlated with asphalt binder performance. Furthermore, high penetration asphalt binders “soft” used for cold climates and low penetration asphalt binders “hard” used for warm climates.
Bitumen 60-70 Softening point and penetration:
Penetration grade bitumen supplied by PUBLTD is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. In addition, it`s produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 60-70 has penetration between 60~70 desi-millimeter also softening point between 48 ~ 52C. The penetration grade bitumen 60/70 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 60/70 has very strong viscosity compare to other grades.
pub-ltd guaranty the quality of Bitumen 60-70 with arrangement of international inspector. Actually For checking the quality and quantity of the bitumen during the loading to vessel and also controlling the production by QC by batch test report before shipping. PUB-LTD guaranty the quality to meet with ASTM/EN 12591.
Drumming facilities majorly located in the Middle East and manufacture high quality new steel drums produced by companies all in conformity to EN DIN standards or ASTM Standards. Bitumen is packed in corrugated, cold rolled steel drums under supervision of QC.
Bulk Bitumen Tanker also availabile on some Global Markets. Also vessels are available for bulk transportation.
pub-ltd exports bitumen penetration grades in drums of various dimensions and weight. We certify proper, to bond shipment and delivery time. Also fine services to client site. pub-ltd team cares about yield, transparency.
