Description of PG Bitumen 76-22
PG Bitumen 76-22 is a high-performance paving-grade asphalt binder classified in the Performance Grade system. It operates under extreme temperatures and consistently exhibits its performance, especially in the high-temperature setting without deforming up to high pavement temperatures of 76°C while having flexibility at low temperatures as low as -22°C. It is applied on high-traffic roads, including highways, airports, and urban roads, where resistance to rutting and fatigue cracking is critical.
PG 76-22 is modified with polymers or other additives to improve its durability, stability, and resistance to oxidative aging, making it suitable for demanding applications and long pavement life.
The main purpose of grading and selecting asphalt binder using the PG system is to make certain that the binder has the appropriate properties for environmental conditions in the field. PG asphalt binders are selected to meet expected climatic conditions as well as traffic speed and volume adjustments.
PG Bitumen 76-22 Application
PG (Performance Grade) Bitumen 76-22 is a high-performance asphalt binder designed for use in regions with extreme temperature variations, particularly in areas with hot climates and moderate cold conditions. Its grading indicates that it can withstand high pavement temperatures up to 76°C without rutting or softening and low temperatures as low as -22°C without cracking.
This makes it ideal for constructing durable roads, highways, and heavy-traffic pavements, especially in areas prone to heavy axle loads and thermal stresses. PG 76-22 is commonly used in polymer-modified asphalt mixes, ensuring enhanced resistance to deformation, fatigue, and thermal cracking.
