Description of bitumen 50/60
Bitumen 50/60 represents a standard penetration grade bitumen that commonly serves as a paving grade bitumen for roadworks and the production of hot-mix asphalt. Derived from the vacuum distillation of crude oil, it undergoes penetration and softening point tests to define its quality. The term “50/60” specifically indicates its penetration range, which falls between 50 to 60 mm/10 at 25°C. Furthermore, this bitumen exhibits thermoplastic properties, softening at higher temperatures and hardening when cooled. This temperature-viscosity behavior plays a crucial role in determining key performance attributes, including adhesion, rheology, durability, and application temperatures.
Uses of bitumen 50/60
Bitumen 50/60 proves suitable for road construction and repairs. It also plays a critical role in producing hot-mix asphalt for bases and wearing courses. Due to its strong properties, this bitumen grade serves as an essential material in various road-building projects, contributing to the durability and stability of the surface. Additionally, its heat resistance makes it particularly useful in tropical regions.
Application of bitumen 50/60
Bitumen 50/60 applies effectively in road construction projects requiring high-performance materials. When used in the production of hot-mix asphalt for bases and wearing courses, it helps create robust, long-lasting pavements. Additionally, it performs exceptionally well in tropical regions, where high temperatures do not soften it. This quality ensures that it retains its properties and does not fail under such conditions.
Softening point and penetration of bitumen 50/60
Jey Pasargad supplies bitumen 50/60, a high-quality petroleum-grade bitumen produced from the residual material left after crude oil cracking and refinement. Bitumen 50/60 has a penetration range between 50 and 70 desi-millimeters, along with a softening point between 52°C and 58°C, It exhibits thermoplastic properties, similar to synthetic resin materials, softening when heated and hardening when cooled. Compared to other grades, bitumen 50/60 offers high viscosity, ensuring durability and resistance.
