Bitumen 30/40

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 Petro Ayegh Espadana Company is produced from the vacuum residue (short residue) feedstock. penetration grade bitumens are specified by the penetration and softening point test. designation by penetration range only. The penetration grade bitumens 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.
This is the hardest of all the grades and can withstand very heavy traffic loads. The characteristics of this grade confirm to that of S 35 grade of IS-73-1992. Bitumen 30/40 is used in specialized applications like airport runways and also in very heavy traffic volume roads in coastal cities.

guaranty and safety of bitumen penetration 30/40

Petro Ayegh Espadana Company guaranty the quality of bitumen penetration grade 30/40 with the arrangement of the international inspector to check quality and quantity of the bitumen penetration grade 30/40 during the loading to the vessel and controlling the production by QC by batch test report before shipping. PAE manufacture guarantees the quality to meet with ASTM.
