Description: 50/70 Penetration Grade Bitumen is derived from the vacuum distillation process of crude oil and is categorized based on its penetration range.
Applications: 50/70 Penetration Grade Bitumen is utilized in the production of hotmix asphalt for base courses and wearing courses.
Properties: 50/70 Penetration Grade Bitumen is a thermoplastic material that gradually softens when heated and solidifies as it cools. This unique temperature/viscosity relationship is essential for determining its performance characteristics and application temperatures. Unlike modified binders, penetration grade bitumen acts as a Newtonian fluid at high in-service temperatures, enabling the establishment of a temperature/viscosity relationship.
Specifications: 50/70 Penetration Grade Bitumen complies with the SANS 4001-BT1:2012 and the European Standard DIN EN 12591:99 specifications for penetration grade bitumen.
