Performance Grade Bitumen 68-22 Features
Performance Grade Bitumen 68-22 is a specially designed Performance Grade Bitumen formulated to perform optimally in regions with hot summers and very cold winters.
Performance Grade 68-22 system assesses bitumen based on its performance at various temperatures, making it a versatile solution for building roads that need to withstand extreme environmental conditions.
The first number (68) indicates the high-temperature performance of the binder. It is capable of handling pavement temperatures up to 68°C, making it ideal for regions that experience high temperatures during the summer months, where the binder needs to maintain its integrity and resist rutting or deformation.
The second number in bitumen pg 68-22 (-22) represents the low-temperature performance. This means that PG 68-22 remains flexible and crack-resistant in temperatures as low as -22°C, which is essential for areas that experience harsh winter conditions and freezing temperatures.
Performance Grade Bitumen is used for high-traffic roads, highways, airfields, and other heavily trafficked pavements where both heat resistance and cold flexibility are required for long-term durability.
