Bitumen comes in various grades, each classified by its penetration value or viscosity. The most commonly consumed grades in the construction industry are:

1. 1. Penetration Grade Bitumen (e.g., 60/70, 80/100)

   This is one of the most widely used bitumen grades in road construction. The penetration grade is defined by the depth at which a standard needle will penetrate the bitumen sample under specific conditions. Penetration Grade 60/70, for instance, is used in moderate climates, offering excellent performance in terms of flexibility, durability, and resistance to deformation.

2. Viscosity Grade Bitumen (VG 10, VG 30, VG 40)

   Viscosity grades of bitumen are widely used in hotter climates, where penetration grades may soften under high temperatures. VG 30 is the most common for road construction, especially in heavy traffic zones due to its higher resistance to deformation and cracking.

3. Performance Grade (PG Bitumen)

   PG bitumen is classified based on performance in specific temperature ranges, making it suitable for extreme climatic conditions. It is commonly used in high-stress applications like highways and airports where pavement performance under varying temperatures is critical.

4. Polymer Modified Bitumen (PMB)

   PMB is bitumen that has been modified with polymers to enhance its elasticity, strength, and resistance to wear. This is particularly useful in regions with heavy rainfall or intense traffic, where standard bitumen grades might fail over time. PMB is highly durable and resistant to cracking and rutting, making it ideal for premium road infrastructure projects.

5. Oxidized Bitumen (Blown Bitumen)

   Oxidized bitumen is produced by blowing air through heated bitumen, which increases its resistance to high temperatures. It is often used in industrial applications such as roofing, pipe coating, and waterproofing.

Major Uses of High Consumption Bitumen Grades

The most common application of high-consumption bitumen grades is in road construction, which accounts for around 85% of global bitumen usage. The flexibility, binding capacity, and water-resistant properties of bitumen make it ideal for creating durable, smooth, and weather-resistant road surfaces. Penetration and viscosity grade bitumens are predominantly used in the construction of highways, streets, and rural roads.

Airports also use performance grade and polymer-modified bitumen in runways and taxiways, where the surface must withstand heavy loads and temperature extremes.

Waterproofing and industrial applications such as roofing membranes, pipe insulation, and protective coatings rely on oxidized bitumen due to its thermal stability and ability to provide long-term moisture barriers.
