Bitumen Penetration 50/70 Definition

Asphalt Penetration Grade 50/70 is a type of bituminous binder used extensively in the construction industry, particularly for road construction and paving. The “50/70” designation refers to its penetration value, which indicates the hardness and consistency of the bitumen.

Characteristics

Penetration Value : The 50/70 grade signifies a penetration range of 50 to 70 decimillimeters (tenths of a millimeter) when a standard needle penetrates the bitumen sample under a load of 100 grams for 5 seconds at 25°C. This range indicates that it is slightly softer than the 40/60 grade, providing a balance between hardness and flexibility.
Viscosity : It has a moderate viscosity, making it suitable for various applications where good flow properties are required during the mixing and laying processes.
Softening Point : Typically ranges from 46°C to 54°C. This is the temperature at which the bitumen softens and starts to flow, which is critical for understanding its performance in different climates.
Ductility : Bitumen 50/70 exhibits good ductility, meaning it can stretch and deform under stress without breaking, which is crucial for preventing cracks in pavements.
Specific Gravity : Approximately 1.01 to 1.06, indicating it is slightly denser than water.

Bitumen Penetration Grade 50/70 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 ZURMUT Co is petroleum grade bitumen, manufactured from fractional / vacuum distillation of crude oil. The Bitumen supplied by ZUMRUT is produced from the vacuum residue (short residue) feedstock. Penetration Grade bitumens are specified by the penetration and softening point test. The designation is by penetration range only. The penetration grade bitumens 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.

 

Asphalt Penetration 50/70 Application
