What is Bitumen 80/100?

80/100 bitumen is also referred to as Pen 80/100 bitumen. It is identified by its penetration value, which determines the firmness of the particular grade of bitumen. The penetration value is obtained from the penetration test, which is an empirical test, giving the depth (in hundredths of mm) to which a weighted needle is capable of penetrating a sample of bitumen under a given load within a specified time and at a defined temperature.

The numbers 80/100 in the designation bitumen 80/100 relate to penetration values likely to be obtained when testing this particular grade of bitumen. In more detail, Bitumen 80/100 has a penetration between 80 and 100 while this value is attained at 25 degrees Celsius and with a 100g load that is applied for a period of five seconds. This range shows that Bitumen 80/100 is of a semi-solid nature and can thus be used across a very broad spectrum.

Properties of Bitumen 80/100

Bitumen 80/100 exhibits several key properties that contribute to its performance and suitability for various applications:

Consistency and Workability: Based on the penetration value, it is correctly termed as Bitumen 80/100, which has a moderate penetration value between 80 and 100 and provides a good consistency that makes it neither too soft for workability when used in constructions or during application processes.

Temperature Susceptibility: Bitumen 80/100 is a type of bitumen material that shows the property of being temperature sensitive. This is the ability to flow or gain a certain viscosity when heat is applied or become very rigid when cold. At high temperatures, it is more pliable than it is at lower temperatures, where it has greater stiffness characteristics and is not easily doable.  

Adhesion and Cohesion: Bitumen is characterized by good, notable adhesive properties, which will help it easily stick to various construction materials, such as aggregates and reinforcement materials. It also boasts good cohesive strength, which helps to achieve the formidable stability and strength of the bituminous mixture.
