Description of bitumen 120/150
Bitumen penetration grade 120/150 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 manufacturing of hot mix asphalt for bases and wearing courses. Penetration grade bitumen supplied by Gold Bitumen is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by us is produced from the 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. The Bitumen mode is dependent on temperature. The temperature-vs-stiffness relationship of bitumen is dependent on the type of crude oil and its refining method. Bitumen penetration grade 120/150 is semi-hard penetration grade bitumen used as a paving grade bitumen which is suitable for road construction and repair. It is also used for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacturing of hot mix asphalt for bases and wearing courses. Bitumen penetration grade 120/150 is one of the most used bitumen grades and it’s a basic material for all other bituminous products. Penetration determines the hardness of bitumen by measuring the depth to which a standard loaded the needle will vertically penetrate in 5 seconds, in a sample of bitumen maintained at a temperature of 25 degrees Celsius.Uses of bitumen 120/150
