Bitumen 60/70 manufacturer and exporter

Bitumen penetration grade 60/70 means the penetration value is in the range 60 to 70 at standard test conditions which commonly
used as a Paving Grade. Bitumen is applicable for the production of hot mix asphalt for bases and pavements and for road
construction. Penetration Grade Bitumen supplied by Tavoil Company This bitumen is produced through aeration on vacuum bottom (the
raw material used for making bitumen left in vacuum distillation column in oil refineries) in bitumen production units. Its
penetration grade ( the measure of bitumen hardness) is between 60 to 70. Bitumen is specified by the penetration and softening
point test. Designing is by penetration range only. The penetration grade bitumen has a thermoplastic property which causes the
material to soften at high temperatures and to harden at lower temperatures. This unique temperature-viscosity relationship is
important when determining the performance parameters such as the adhesion, rheology, durability and application temperatures of
bitumen.

The Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of
crude oil and its refining method. Bitumen penetration grade 60/70 is semi-hard penetration grade bitumen used as a paving grade
bitumen which is suitable for road construction and repair. It is also used for the production of asphalt pavements with the below
technical specification. This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing
courses. Bitumen 60/70 is one of the most used bitumen grades and it’s a basic material for all other bituminous products.
Penetration determines the hardness of bitumen by measuring the depth to which a standard loaded the needle will vertically
penetrate in 5 seconds, in a sample of bitumen maintained at a temperature of 25 degrees Celsius.

Bitumen Penetration grade 60/70 Applications
Bitumen 60/70 is suitable for road construction and for the asphalt pavements with superior properties. This type of bitumen used
in the manufacture of hot mix asphalt for bases and wearing courses and the main usage of this product is used in the road in mild
regions. The bitumen is provided during the presses of oxidation of vacuum bottom in bitumen production units. Due to its medium
air blowing and penetration, it is used in mild areas.
