Description of Bitumen 20/30
Bitumen Penetration Grade 20/30 is a standard Hard penetration grade Bitumen usually used as a Paving Grade Bitumen suitable for road construction and for the production of asphalt pavements with superior properties. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses. Penetration Grade Bitumen is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen is produced from vacuum residue (short residue) feedstock. Penetration Grade bitumen are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumen have a thermoplastic property which causes the material to soften at high temperatures and to harden at lower temperatures. This unique temperature/ viscosity relationship is important when determining the performance parameters such as the adhesion, rheology, durability, and application temperatures of bitumen.
Properties of Bitumen Penetration Grade 85/100
Penetration grade bitumen 20/30 supplied by HJ Oil is pure petroleum grade bitumen, manufactured from vacuum bottom by passing hot air. The bitumen supplied by HJ Oil is produced from remain of crude oil after cracking and removing hydrocarbon. Penetration grade bitumen 20/30 has penetration between 20~30 desi-millimeter and the softening point between 55~63 C.
The penetration grade bitumen 20/30 has a thermoplastic property which is like synthetic resin material which gets softer with heating and hardens when cooled. Penetration grade bitumens are specified by the penetration and softening point test. The temperature-vs-stiffness relationship of bitumen is dependent on the source of crude oil and the method of refining.
Bitumen penetration grade 20/30 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 specifications.
Bitumen Penetration Grade 20/30 Applications
Bitumen 20/30 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 85/100
HJ OIL guarantees the quality of bitumen penetration grade 20/30 with the arrangement of the international inspectors to check the quality and quantity of the bitumen penetration grade 20-30 during the loading to the vessel and controlling the production by QC by batch test report before shipping.
HJ Oil guarantees that the Bitumen Grade 20/30 is produced in compliance and conformity to International of European Standard DIN EN 12591:99, also meets the requirements of the following specification.
Packing of Bitumen 20/30
Paving Bitumen 20/30 is commonly packed in new steel drums, 150, 180 & 220 Kg barrels, and 1MT and 500Kg Jumbo Bags or 300kg Bitubag.
Likewise, the rest of the grades are ready to load Ex-work bulk by truck.
