Explanation of Bitumen penetration grade 120/150
Bitumen Penetration Grade 120/150 is a typical penetration grade Bitumen that is typically used as a paving grade Bitumen appropriate for building roads and creating asphalt pavements with exceptional qualities. The primary application for this grade of bitumen is the production of hot mix asphalt for bases and wearing courses. Petroleum-grade bitumen produced from fractional or vacuum distillation of crude oil is the penetration-grade bitumen that Petro Bitumen Company supplies. The feedstock for the production of the bitumen that Petro Bitumen Company provides is hoover residue (short residue). The penetration and melting point test is used to define the bitumens of the penetration grade. The classification is based only on the penetration range. The substance softens at high temperatures and hardens at lower temperatures because of the thermoplastic feature of penetration-grade bitumen. When calculating bitumen performance factors like adhesion, rheology, durability, and application temperatures, it’s crucial to take into account this particular temperature/viscosity relationship.
It is very important once it binds the aggregates and gives the bituminous mix a special cohesion and stability. Penetration Grade Bitumen is a conventional bitumen that is usually utilized as a Paving Grade Bitumen necessary for road construction and for the manufacturing of asphalt pavements with exceptional characteristics.
Using bitumen penetration grade 120/150
The asphalt surfaces with exceptional qualities can be made with bitumen 120/150 for use in road construction. For foundations and driving courses, this kind of bitumen is utilised to create hot-mix asphalt.
Bitumen penetration pledges and protection
The arrangement of the international inspectors to check both the quality and quantity of the bitumen penetration grade 120/150 throughout its shipment to the boat along with monitoring the production by QC by batch test report before shipping allows Petro Bitumen Company to guarantee the quality of its product. The Petro Bitumen Company promises the quality will fulfill the requirements of the ASTM.
