BITUMEN 30/40

Definition of bitumen penetration grade 30/40

It is a kind of bitumen and standard penetration grade. This type is petroleum grade bitumen, manufactured from fractional- vacuum destination of crude oil. The bitumen penetration grade 30/40 supplied by BITUMENSHOP Company is produced from the vacuum residue (short residue) feed-stock. Penetration grade bitumen’s are specified by the penetration and softening point test. Designation by penetration range only. The penetration grade bitumen’s have a thermoplastic property which causes the material to soften at high temperatures and to harden at low temperatures.

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 30/40 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 penetration grade 30/40 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.

Application of bitumen penetration grade 30/40

Bitumen 30/40 is suitable for road construction and repair for the asphalt pavements with superior properties. This type of bitumen used in the manufacture of hot mix asphalt for bases and wearing courses.
