Description of PG Bitumen 76-16
PG Bitumen 76-16 has been a high-performance grade applied to areas where severe climate conditions and traffic load occur. It is a type of bitumen classified under the Performance Grade system, which is basically utilized to classify asphalt binders based on performance at specific temperature ranges. The “76-16” designation means this bitumen is so engineered to bear the highest temperature of up to 76°C and the lowest temperature of -16°C without losing its structural integrity or function.
One of the major advantages of PG 76-16 is its increased durability against rutting and deformation under heavy loads at high temperatures. This makes it ideal for a wide range of applications in infrastructure, including highways and airports, where long-lasting performance is indispensable. The superior elasticity and flexibility of this bitumen result from its polymer-modified nature, which helps it accommodate thermal expansion and contraction while ensuring a strong bond with aggregate materials.
PG Bitumen 76-16 Application
PG Bitumen 76-16 has widespread applications in several fields, such as highways, urban roads, airport runways, and industrial pavements. It is highly effective in high-temperature applications for areas that are always in the intense sunlight and subjected to heavy vehicular traffic, and its low-temperature flexibility makes it durable in colder climates. It is also used in overlay projects and maintenance activities in order to prolong the lives of pavements.
Packaging
PG 76-16 is normally supplied in bulk tankers, drums, or special containers to ensure safe and efficient transportation. The packaging is designed to maintain the quality and integrity of the material during transport and storage. Proper handling and storage practices are required to avoid contamination and ensure optimal performance at application.
