Types of bitumen:

Bitumen varieties
Although bitumen has several uses, over 90% of demand is met by its usage in the direct building and maintenance of roads or through the use of asphalt. Bitumen emulsions, cutback bitumen, and paving grades are important bitumen varieties for use in road applications. Paints, sealants, adhesives, enamels, waterproofing, electrical goods, flooring materials, back carpet tiles, land and marine pipe coatings, and countless more non-road applications employ hard, oxidized, and blown grades as well as mastic asphalt. Recently developed polymer-modified bitumen (PMB) is finding increasing use in both paving and non-road applications. Road paving is the main use of bitumen, even if there are many non-road applications and they only use minor amounts. Therefore, infrastructure cuts have had a huge influence on the world’s demand for bitumen.


Types of Bitumen

Some common types of bitumen include:

  1. Penetration grade bitumen: This is a traditional type of bitumen that is obtained by the penetration of a sample of bitumen at a specific temperature and then measuring the depth of penetration.
  2. Performance grade (PG) bitumen: This type of bitumen is graded based on its performance at different temperatures. The grades are identified by a two-digit number, with the first digit indicating the low-temperature performance and the second digit indicating the high-temperature performance.
  3. Cutback bitumen: This type of bitumen is made by dissolving bitumen in a solvent. It is used as a binder in road construction and is particularly useful in cold weather.
  4. Emulsified bitumen: This type of bitumen is made by suspending droplets of bitumen in water. It is used as a binder in road construction and is particularly useful in hot weather.
  5. Polymer modified bitumen (PMB): This type of bitumen is made by adding polymers to bitumen to improve its performance. PMB is more resistant to rutting and fatigue cracking, and it has a higher softening point than regular bitumen. Polymer modified bitumen (PMB) is a type of bitumen that is enhanced by the addition of polymers. This modification process significantly improves the performance of the bitumen, making it more resistant to rutting and fatigue cracking. One notable advantage of PMB is its higher softening point compared to regular bitumen. This makes it particularly suitable for areas with high temperatures, ensuring its stability and durability.

Types of Bitumen/Asphalt <br data-mce-bogus=1> Bitumen, also commonly referred to as asphalt, is a highly viscous, black or dark brown solid or semi-solid material. It is primarily used for road construction, waterproofing, and various industrial applications. There are different types of bitumen available, each with its own specific characteristics and uses. One common type is bulk bitumen, which is typically purchased in large quantities for major construction projects. Bulk bitumen is often used to create asphalt mixtures for road surfaces, providing durability and resistance to heavy traffic. With its diverse range of applications and importance in infrastructure development, bitumen plays a crucial role in the construction industry.


The most commonly used type of bitumen in the construction industry is known as bulk bitumen. It is widely utilized for various applications, including road surfacing, pavement construction, and waterproofing. Bulk bitumen is favored due to its excellent adhesive properties and durability, making it suitable for withstanding heavy traffic loads and harsh weather conditions. Additionally, its versatility allows for easy mixing with aggregates to create high-quality asphalt mixes. Overall, bulk bitumen is the preferred choice for its reliability and performance in construction projects.
