Elucidation of Bitumen penetration grade 160/220
Bitumen Penetration Grade 160/220 is a typical penetration grade bitumen that is used as paving grade bitumen for making asphalt pavements with outstanding qualities and for building roads. Hot mix asphalt for bases and wearing courses is mostly made with this grade of bitumen. Petroleum grade bitumen, or penetration grade bitumen, is produced through fractional or vacuum distillation of crude oil and is provided by Petro Bitumen Company. The vacuum residue (short residue) feedstock is used to generate the bitumen that the Petro Bitumen Company provides. The penetration and softening point tests are used to define penetration grade bitumens. Only the penetration range is used to designate. The thermoplastic feature of penetration grade bitumens leads the substance to soften at high temperatures and harden at lower temperatures. When defining bitumen performance factors including adhesion, rheology, durability, and application temperatures, this particular temperature/viscosity connection is crucial.
Type of Penetration Bitumen is a common type of bitumen used for paving. When bitumen binds the aggregates and gives the bituminous mix a distinctive cohesiveness and stability, it becomes crucial for road building and the creation of asphalt pavements with excellent qualities.
Bitumen penetration grade 160/220 application
Bitumen penetration 160/220 is appropriate for asphalt pavements with exceptional qualities and for building roads. The production of hot mix asphalt for bases and wearing courses uses this kind of bitumen.
Bitumen penetration 160/220 is guaranteed to be safe.
Petro Bitumen Company ensures the quality of bitumen penetration grade 160/220 by arranging for international inspectors to verify the quality and quantity of bitumen penetration grade 160/220 during the loading of the vessel and QC to control production by batch test report before shipping. The Petro Bitumen Company warrants that the quality will satisfy ASTM.
