Bitumen Temperature and Its Properties

Bitumen's state depends on temperature. The relationship between temperature and bitumen stiffness varies based on the type of crude oil and refining method.

60/70 Penetration Grade Bitumen

60/70 penetration grade bitumen is a semi-hard bitumen used as asphalt pavement for road construction. It is also applied for producing asphalt coatings. This grade of bitumen is primarily used in producing hot mix asphalt for base layers and surface coating. Bitumen 60/70 is one of the most widely used grades and serves as the base material for all other bitumen products.

Temperature Dependence

The condition of 60/70 bitumen depends on its temperature. The relationship between temperature and hardness of bitumen depends on the type of crude oil and its refining process. The penetration grade of 60/70 bitumen ranges from 6 to 7 millimeters. Semi-hard penetration bitumen is suitable for heavy applications, including road construction and repair.

Applications of 60/70 Bitumen

60/70 bitumen is used for asphalt production and is mainly applied in hot mix asphalt for surface coating. This type of bitumen is the most common grade and is used as a raw material for producing other bitumen products.

Bitumen Properties

The penetration grade bitumen offered by Dorsa Bitumen is pure petroleum bitumen produced by passing hot air through vacuum bottom raw material. Bitumen is derived from the residues of crude oil after decomposition and the removal of hydrocarbons.

Viscosity

60/70 penetration grade bitumen has a penetration range of 6 to 7 millimeters and a softening point between 49 and 56 degrees Celsius.

Impact of 60/70 Bitumen

60/70 bitumen has thermoplastic properties similar to synthetic resin. It softens when heated and hardens when cooled. This grade of bitumen has significantly stronger viscosity compared to other grades and is widely used.
