Definition of bitumen penetration grade 160/220
Bitumen Penetration Grade 160/220 is a standard 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 supplied by Petro Ayegh Espadana Co is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by Petro Ayegh Espadana Co is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumen’s are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumen’s 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.
Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it’s very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.
