Bitumen 60/70, often referred to simply as Bitumen 60-70, is a grade of bitumen that falls within a specific range of penetration and viscosity. The numbers 60 and 70 signify the penetration range in decimillimeters (0.1 mm) that the bitumen exhibits at a particular temperature. The penetration value indicates the consistency of the bitumen – how soft or hard it is – and is determined by measuring the depth to which a standard needle penetrates the bitumen under standard conditions.
Properties of Bitumen 60/70
Penetration: Bitumen60/70 has a penetration value of 60 to 70 at 25°C. This means it has a relatively medium consistency, making it suitable for a variety of applications.
Viscosity: The viscosity of Bitumen 60/70 is moderate, making it easy to handle and mix with aggregates during asphalt production.
Thermal Susceptibility: This grade of bitumen possesses good thermal susceptibility, allowing it to adapt to temperature fluctuations without significant changes in its properties.
Adhesion: Bitumen60/70 exhibits excellent adhesion properties, making it a preferred choice for waterproofing and sealing applications.
