bitumen 30/40

description

Bitumen 30/40 is a kind standard penetration grade bitumen. The bitumen penetration grade 30/40 supplied by Bitumen Malaysia is produced from the vacuum residue (short residue) feedstock. Penetration grade bitumens are specified by the penetration and softening point test. Penetration grade bitumens have a thermoplastic property which causes the material to soften at high temperatures and to harden at low temperatures.
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 technical specifications listed below. 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.
ADTM bitumen penetration grade 30/40 is hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.

applications

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. Bitumen Kian’s bitumen 30/40 is fully qualified and guaranteed through the expertise of our international inspectors to ensure the quality meets the industry standards. Bitumen Kian’s bitumen is guaranteed to meet the international standard of ASTM.

Specification

Softening point and penetration of bitumen 30/40: Penetration grade bitumen supplied by ATDM is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by ATDM is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 30/40 has penetration between 35~50 desi-millimeter and softening point between 55 ~ 63 C. The penetration grade bitumen 30/40 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 30/40 has very strong viscosity compare to other grades.

Guaranty|warranty of bitumen 30/40: ATDM guaranty the quality of bitumen 30/40 with arrangement of international inspector to check quality and quantity of the bitumen during the loading to vessel and controlling the production by QC by batch test report before shipping. ATDM guaranty the quality to meet with ASTM/EN 12591.
