Description of PG Bitumen 70-10
PG Bitumen 70-10 is tailored for regions characterized by mild climates and minimal temperature fluctuations. With its exceptional flexibility and crack resistance, this grade ensures the longevity of pavement surfaces even in areas with relatively low thermal stress. Its ability to maintain structural integrity under varying weather conditions makes it a reliable choice for road construction projects in temperate climates. Whether facing moderate traffic loads or occasional temperature changes, PG-70-10 bitumen offers durable pavement solutions, reducing the need for frequent maintenance and repairs.
PG Bitumen 70-10 Application
PG Bitumen 70-10 is one of the high-performance bitumen binders in the construction and maintenance of roads, particularly in areas of very fluctuating climatic conditions. Thus, the “70-10” indicates that the performance covers a broad range of temperatures: it could be resistant to high temperatures up to 70°C without showing softening, yet serviceable at low temperatures as low as -10°C without cracking. It is, therefore, ideal for application in the construction of highways, runways, and urban roads of those regions where summers are usually hot and winters mild. It provides higher resistance to deformation under heavy traffic loads, increasing the life and quality of paved surfaces.
Besides road construction, PG 70-10 finds its application in specialized operations like waterproofing and roofing, owing to the characteristics that it has in regard to adhesiveness and weather resistance. It resists aging, too, and retains its consistent quality for long periods, hence limiting occurrences of repair needs. Its versatility as a material means that the asphalt mixes are modified to bind into specified engineering requirements, such as polymer-modified asphalt.
Packing
PG 70-10 is normally presented in various packages as required by the demands of the Construction Industry. Some of them include bulk supply: large-scale projects, it is dispatched at the required site in heated tanker trucks, drum packaging: wherein the bitumen is packed into the steel drums for easy storing and movements.
In addition, bitumen is also packed in polybags or jumbo bags with an inner lining to prevent leakage and for safe handling. The choice of packaging depends on the project scale, logistics, and storage requirements; all are designed to maintain the material’s quality and usability during transit and storage.
