Definition of bitumen penetration grade 85/100
Asphalt infiltration grade 85/100 is a standard infiltration asphalt normally used as road asphalt suitable for road construction and asphalt pavement production, with excellent properties. This type of bitumen is mainly used for the production of heated asphalt for roadbeds and surface grades. Infiltrated asphalt supplied by Petro Bitumen Company is a petroleum grade asphalt produced by fractionation/vacuum distillation of crude oil. Asphalt is supplied by the Petro Bitumen Company. This asphalt is produced by vacuum bottom aeration in an asphalt manufacturing plant (raw material used to make asphalt left over in refinery vacuum distillation towers). Penetration (a measure of asphalt hardness) is 85-100.
Penetration grade bitumen is specified by penetration and softening point tests. This designation refers only to the penetrating area. Penetration grade asphalt has thermoplastic properties, with the material softening at high temperatures and hardening at low temperatures. This unique temperature-viscosity relationship is important in determining asphalt performance parameters such as adhesion, rheology, durability and application temperature. Asphalt mode is temperature dependent. The temperature-to-stiffness ratio of asphalt depends on the type of crude oil and the method of refining. Asphalt Penetration Grade 85/100 is a semi-rigid penetrating asphalt used as road construction asphalt, suitable for road construction and road rehabilitation. It is also used in the production of asphalt pavements with the technical specifications given below. This type of asphalt is mainly used to produce heated asphalt for roadbeds and surfacing. Asphalt 85/100 is one of the most commonly used types of asphalt and is the base material for all other asphalt products.
Penetration measures the hardness of asphalt by measuring the vertical penetration depth of a standard load stylus for 5 seconds into a sample of asphalt maintained at a temperature of 25 degrees Celsius.
Application of bitumen penetration grade 85/100
Bitumen 85/100 has excellent properties and is suitable for road construction and asphalt paving. This type of asphalt is used for the production of hot asphalt for roadbeds and surface layers. The primary use for this product is spray and grit applications. Asphalt is fed from vacuum soil during the oxidation press of an asphalt manufacturing plant. Due to its relatively shallow depth of air injection and penetration, it is used as a pavement and insulation material in cold climates. It does not crack even at low temperatures.
Guaranty and safety of bitumen penetration 85/100
Petro Bitumen Company ordered international inspectors to check the quality and quantity of asphalt penetration class 85/100 during loading onto vessels and to control production by quality control using batch test reports in advance This guarantees quality of asphalt penetration class 85/100. send. Petro Bitumen Company guarantees quality according to ASTM.
