Description Of Bitumen Penetration Grade 30/40
The bitumen penetration grade 30/40 supplied by HJ OIL Co. 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.
The bitumen penetration grade 30/40 is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses.This Bitumen 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 25degrees Celsius.
Applications Of Bitumen Penetration Grade 30/40
Bitumen penetration grade 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.
Guaranty and Safety of Bitumen Penetration Grade 30/40
Bitumen penetration grade 30/40 is suitable for road construction and repair for the asphalt pavements with superior properties. It is also used for hot mixed asphalt because of the properties of very strong viscosity compared to other grades.
