Performance Grade Bitumen
Performance Grade Bitumen
PG Bitumen is an advanced paving bitumen classified according to its performance under specific temperature and loading conditions. This system evaluates the bitumen’s ability to resist rutting at high temperatures, fatigue cracking at intermediate temperatures, and thermal cracking at low temperatures.
Common grades such as PG 58-22, PG 64-22, and PG 76-10 are produced in accordance with AASHTO M320, ensuring reliable performance, durability, and long term behavior in modern asphalt pavement applications.
What is Performance Grade Bitumen?
Performance Grade Bitumen, commonly known as PG Bitumen, is an asphalt binder classification system developed to evaluate binder performance under specific temperature and environmental conditions.
The Performance Grade system considers the expected pavement temperature and traffic conditions to help engineers select an appropriate binder for a specific road project.
PG grades are commonly expressed using two temperature values, such as Performance Grade 70-16, where the first number represents the high-temperature performance and the second represents the low-temperature performance of the binder.
This performance-based approach helps improve asphalt pavement durability, resistance to rutting, and resistance to temperature-related cracking.
PG Bitumen Grades:
Bitumen Performance Grade 70-10
A high temperature performance grade designed for hot climatic conditions and demanding road applications. PG 70-10 provides reliable resistance to rutting and permanent deformation, making it suitable for highways and heavy traffic.
Bitumen Performance Grade 70-16
A versatile performance grade developed for warm climates with moderate low-temperature requirements. PG 70-16 offers balanced resistance to rutting and cracking, making it suitable for highways and heavily trafficked urban roads.
Bitumen Performance Grade 76-10
A high performance bitumen designed for very hot climates and demanding pavement conditions. PG 76-10 provides strong resistance to rutting and deformation, making it suitable for heavy traffic and high-temperature road applications.
Applications of PG Asphalt Binders
This type of Bitumen is primarily used in asphalt pavement and road construction projects where resistance to temperature and traffic-related stresses is important.
Common applications include:
- Highways and expressways
- Heavy-traffic roads
- Urban roads and intersections
- Airport runways
- Asphalt pavement rehabilitation
- Industrial and commercial roads
- Roads exposed to extreme temperatures
Benefits of PG Binders
Improved Rutting Resistance
PG binders are designed to provide improved resistance to permanent deformation under high pavement temperatures and heavy traffic.
Better Temperature Performance
PG Bitumen allows engineers to select a binder based on the expected temperature conditions of the pavement.
Improved Pavement Durability
Selecting the appropriate PG grade can contribute to longer-lasting asphalt pavement and reduced maintenance requirements.
Climate-Based Selection
PG bitumen grades help match asphalt binder performance with the climatic conditions of the project location.
Suitable for Heavy Traffic
Higher PG grades can be selected for roads exposed to heavy traffic and high pavement temperatures.
How to Choose the Right PG Grade?
Selecting the appropriate Performance Grade Bitumen depends on several factors, including pavement temperature, climate, traffic volume, traffic loading, and project specifications.
For projects in hot climates or roads exposed to heavy traffic, a higher high-temperature PG grade may be required to improve resistance to rutting. In colder climates, a suitable low-temperature grade is important to reduce the risk of thermal cracking.
The appropriate PG grade should therefore be determined based on the project’s climatic conditions, traffic requirements, and applicable asphalt specifications.
PG Asphalt Binder
PG Asphalt Binder is a performance-based asphalt binder designed to provide reliable pavement performance under specific temperature and traffic conditions. Unlike conventional penetration grade bitumen, Performance Grade binders are classified according to their ability to resist temperature-related stresses, including rutting at high temperatures and thermal cracking at low temperatures.
PG Asphalt Binder is commonly used in highway construction, heavy-traffic roads, airport pavements, and other asphalt applications where long-term durability and resistance to deformation are important. The appropriate PG grade is selected based on the expected pavement temperatures, climate, traffic loading, and project specifications.

What is Performance Grade Bitumen?
Performance Grade Bitumen is an asphalt binder classified according to its expected performance at specific high and low pavement temperatures.
What does Performance Grade 70-16 mean?
Performance Grade 70-16 indicates a binder designed for high pavement temperatures up to approximately 70°C and low pavement temperatures down to approximately -16°C.
What is the difference between PG Bitumen and 60/70 Bitumen?
PG Bitumen is classified based on performance at specific pavement temperatures, while 60/70 is a penetration grade classified primarily according to penetration characteristics.
Which PG grade is suitable for hot climates?
Higher high-temperature PG grades, such as PG 70 or PG 76, may be suitable for hot climates and heavily trafficked roads. The final grade should be selected according to pavement temperature, traffic loading, and project specifications.
Can ASA Bitumen provide laboratory test reports?
What packaging options are available?
Performance Grade Bitumen can be supplied in steel drums, jumbo bags, or bulk shipment, depending on the grade, quantity, destination, and shipping requirements.
What is PG Bitumen used for?
PG Bitumen is primarily used in asphalt pavement and road construction projects where resistance to high temperatures, low temperatures, heavy traffic, and pavement deformation is required.
Is PG Bitumen suitable for hot climates?
Yes. PG Bitumen is particularly useful in hot climates because the PG system allows the asphalt binder to be selected according to the expected pavement temperature. Higher high-temperature PG grades may provide improved resistance to rutting.
Is PG Bitumen suitable for heavy traffic roads?
Yes. Higher Performance Grade binders can be selected for roads exposed to heavy traffic and high pavement temperatures. The appropriate grade should be determined based on traffic conditions and project specifications.
Can PG Bitumen be used for asphalt production?
Yes. PG Bitumen is widely used as an asphalt binder in hot mix asphalt and other asphalt pavement applications. The selected PG grade should match the requirements of the specific pavement project.
