PERFORMANCE GRADE BITUMEN (PG BITUMEN)
INTRODUCTION OF PERFORMANCE GRADE BITUMEN (PG BITUMEN)
Performance grade bitumen (PG Bitumen) is a kind of bitumen that is rated according to how it performs under certain performance conditions. This classification, which is based on an understanding of bitumen’s behavior and functional characteristics, has been evaluated, and the appropriate bitumen types have been determined. These characteristics include resistance to deformations, resistance to cracking due to cold, resistance to cracking due to fatigue, and the ability to predict how bitumen will harden in an asphalt factory and when preparing the asphalt mixture, as well as how it will harden over time and in response to tests specified in the specifications.
Each kind of bitumen is identified by two positive and negative values, the positive number representing the median of the highest pavement temperature over the previous seven days and the negative number representing the lowest pavement temperature in degrees Celsius. For instance, a bitumen is created such that it may be utilized in environments with an average maximum temperature of 52 and a minimum temperature of -40 during the course of a week. Grading of Performance Since it is mostly used for paving, it should take into account the real circumstances of various paving projects, such as the strain relationship under the field load, traffic speed and volume, and the pavement structure. petro naft company produces and supplies different grades of this product.
WHAT IS PERFORMANCE GRADE BITUMEN (PG BITUMEN)?
Performance Grade bitumen (PG BITUMEN) is categorized based on its high-temperature performance. It resists deformation under high traffic, especially in hot areas.
The high-temperature grade of PG bitumen assesses its resistance to rutting and deformation at high temperatures, whereas the low-temperature grade measures its cracking and stiffness at low temperatures.
A sample of PG bitumen is rheologically tested at different temperatures and shear rates to establish its high-temperature grade. These experiments replicate bitumen stresses and strains under varying traffic and temperature conditions. The results of these tests establish the high-temperature grade, which is a number between 16 and 46, with higher values indicating greater performance at high temperatures.
The low-temperature grade of PG bitumen is established by testing a sample at low temperatures to detect stiffness and cracking resistance. The results of these tests establish the low-temperature grade, which is a number between -22°C and -76°C, with lower values indicating greater performance at low temperatures.
PG bitumen gives a more accurate and dependable technique to create asphalt pavements that can handle high traffic and harsh temperatures.

PERFORMANCE GRADE BITUMEN (PG BITUMEN) HS CODE, CHEMICAL FORMULA AND CAS NUMBER
Performance Grade Bitumen, commonly referred to as PG Bitumen, is a high-quality form of asphalt that is engineered to withstand specific climatic conditions. The Harmonized System (HS) code for PG Bitumen is 27132000, indicating its trade classification as bituminous or oil shale and tar sands. While it’s difficult to provide an exact chemical formula due to its complex mix of hydrocarbons, the primary components are carbon, hydrogen, sulfur, and traces of nitrogen and oxygen. This asphalt product doesn’t have a specific CAS number since it’s a blend of many different hydrocarbons, not a single chemical entity.
PERFORMANCE GRADE BITUMEN (PG BITUMEN) PRODUCTION PROCESS
In the realm of pavement engineering and road construction, Performance Grade (PG) Bitumen, also known as Asphalt Binder, stands as an essential material. This superior grade of bitumen, compared to traditional penetration grade bitumen, offers enhanced performance characteristics, making it the preferred choice for robust and durable road surfaces.
The production process of PG Bitumen involves four crucial steps: distillation, air blowing, polymer modification, and finally, rigorous testing.
Initially, crude oil is subjected to an atmospheric distillation process at around 350°C. The lighter hydrocarbons vaporize, leaving the heavier hydrocarbons, also known as bitumen feedstock or vacuum bottoms.
2. Air Blowing:
The bitumen feedstock is then sent to a bitumen blowing unit, where hot air is introduced. The oxygen reacts with the feedstock, leading to changes in the bitumen’s physical properties – a process often called “oxidation”. The end result is oxidized bitumen.
3. Polymer Modification:
To enhance the performance properties of the bitumen, it is blended with specific polymers. Commonly used polymers include Styrene-Butadiene-Styrene (SBS) and Atactic Polypropylene (APP). The inclusion of these polymers improves the bitumen’s elasticity, thermal properties, and resistance to deformation.
The final step is extensive testing to confirm that the PG Bitumen meets the required specifications. Tests are conducted to examine its rheological properties, including the bitumen’s response to different temperatures and loading times. These characteristics determine the performance grade of the bitumen.
The production of PG Bitumen is a science in itself, requiring precision, advanced technology, and an understanding of the properties of crude oil and polymers. The outcome is a high-quality bitumen that’s instrumental in the creation of superior road infrastructure, contributing to safer and smoother journeys.
PERFORMANCE GRADE BITUMEN (PG BITUMEN) HISTORY
The Strategic Highway Research Program (SHRP) in the United States performed a Project between 1987 and 1993 to address the limitations of empirical systems after viscosity and penetration-based grading methods were demonstrated to be unsatisfactory. The major topics of this program were the improvement of performance and durability, as well as the safety of asphalt roads in the United States. This program examined the presentation of bitumen performance standards, and bitumen laboratory evaluation and measurement were implemented as a strategy to predict bitumen’s long-term performance in asphalt. This program imitated real-world conditions in asphalt over a long period of time in order to enhance the performance of generated bitumen during testing and minimize failures such as rutting and cracking of asphalt at low temperatures or asphalt fatigue. This enables long-term forecasting of how bitumen in asphalt will behave or function. The ultimate result of a system for analyzing and projecting bitumen performance by reproducing laboratory settings to bitumen’s actual environmental conditions is performance grade bitumen, or PG bitumen.
One of the project’s outcomes was a performance-based binder specification based on a new set of tests. Grade for PG Bitumen is graded based on how well it behaves at different temperatures. Binders are classified as performance grade (PG) bitumen in the Super Pave grading system depending on how well they perform in very hot and cold regions. The primary goal of grading and selecting an asphalt binder is to ensure that it has the appropriate properties for the location in which it will be utilized. The PG asphalt binders are selected to correspond to the expected weather conditions, volume variations, and traffic speed. As a consequence, the PG technique includes a battery of tests to assess the physical properties of the binder, which are directly related to how well it performs during paving.
The Long-Term Pavement Performance (LTPP) has offered a controlled way for computing and determining the temperature of the pavement based on the temperature of the air above. This indicates the temperature range of the pavement, and the bitumen that works best under the particular conditions is selected. The ability of penetration grading and viscosity grading to properly define asphalt binder for use in Hot Mix Asphalt (HMA) pavement is limited. As a consequence, as part of the Superpave research, new specifications and binder tests were developed to more accurately and comprehensively determine the qualities of asphalt binders to be used in HMA pavements. The majority of these tests and criteria are designed to solve HMA pavement performance issues such as heat cracking, rutting, and fatigue cracking. The idea behind Superpave performance Grade (PG) Bitumen is that the attributes of an HMA asphalt binder should be appropriate for the situations in which it is employed. This considers aging difficulties as well as expected climatic conditions for asphalt binders, for example. As a result, the PG system employs a standard set of tests (similar to those used in penetration and viscosity grading systems), but it also requires that a specific asphalt binder pass these tests at specific temperatures that vary depending on the unique climatic conditions in the area of application. Although the concept is not new, the Superpave PG method generates more complete and accurate connections between asphalt binder characteristics and application situations.

PERFORMANCE GRADE BITUMEN (PG BITUMEN) NOMENCLATURE
The traffic volume and pavement temperature are used to classify Performance Grade Bitumen (PG BITUMEN). In order to extend the life of the pavement and improve its quality, the modification and monitoring carried out here are intended to replicate environmental factors and traffic levels. Two figures that indicate the pavement temperatures serve as the basis for the PG grading system. The first number, for instance, “PG 64-XX,” stands for the greatest pavement temperature in Celsius, while the second number, for instance, “PG XX-22,” stands for the lowest. Just keep in mind that these are pavement temperatures, not air temps (these pavement temperatures are derived from air temperatures using an algorithm included in the LTPP Bind program). The consequences of rutting are tied to high temperatures, whereas fatigue cracking is associated to low temperatures.

The low-temperature grade, based on the minimum pavement design temperature, signifies the bitumen’s resistance to thermal cracking.
2. Polymer Modification:
If the binder contains polymers, it will have an “S” designation (e.g., PG 58S-22). Polymer modified bitumen provides enhanced elasticity, higher resistance to temperature and aging, and better adhesion properties.
3. Performance Tests:
Performance tests for PG Bitumen include:
- Rutting Factor (G/sinδ):* This measures the bitumen’s resistance to permanent deformation or rutting. Higher values indicate better resistance.
- Fatigue Factor (G*sinδ): This test is designed to measure the binder’s ability to resist fatigue cracking.
- Creep Stiffness (S) and m-value: These parameters test the low-temperature properties of the bitumen, specifically its resistance to thermal cracking.
4. Binder Grade:
The binder grade is identified by two numbers (e.g., PG 58-22). The first number represents the average 7-day maximum pavement design temperature (in °C), and the second number stands for the minimum pavement design temperature expected in the region.
By adhering to these specifications, road engineers can ensure that the PG Bitumen used in their projects will deliver the best performance under the specific conditions of their region.
