Bitumen 60/70 Specifications
In this article, I will discuss the specifications of Bitumen 60/70 in detail.
Bitumen 60/70 is bitumen that is often used in the building and road paving industries. It is renowned for having medium penetration and viscosity properties, which make it appropriate for a variety of applications.
?Due to its unique qualities and features, bitumen 60/70 is a bitumen grade that is often utilized in construction and road paving. It is excellent for a variety of applications due to its penetration value, softening point, ductility, penetration index, specific gravity, and other characteristics. For the purpose of creating high-quality and long-lasting road surfaces and other construction projects, Bitumen 60/70 must adhere to these requirements. Additionally, its performance grade (PG) categorization aids engineers and builders in choosing the appropriate bitumen grade for certain temperature and climatic circumstances, assuring safety and durability in building projects. Overall, for effective and sustainable infrastructure development, it is crucial to comprehend and abide by the Bitumen 60/70 criteria.
Bitumen 60/70 is distinguished by its penetration value, which is the depth (measured in tenths of a millimeter) to which a standard needle can pierce a bitumen sample under certain circumstances. Bitumen 60/70 generally has a penetration value between 60 and 70 units. This number represents the consistency and hardness of the bitumen.
Softening Point: Bitumen 60/70's softening point is another crucial feature. This is the temperature at which bitumen liquefies and softens. Bitumen 60/70 typically softens at a temperature between 48 and 52 degrees Celsius. This characteristic is important because it establishes the temperature at which bitumen may be used successfully in building and road paving operations.
Ductility: The capacity of bitumen to stretch and bend without breaking is known as ductility. At 25 degrees Celsius, bitumen 60/70 generally has a minimum ductility of 100 cm. This characteristic is crucial because it guarantees that the bitumen can endure the pressures and stresses involved in building roads and other uses.
Penetration value: Bitumen 60/70's vulnerability to temperature is evaluated using its penetration index. The penetration value at 25 degrees Celsius is divided by the penetration value at 0 degrees Celsius to arrive at the result. For Bitumen 60/70, a penetration index value of 0.9 to 1.1 is regarded as appropriate. This shows that bitumen retains its consistency and functionality throughout a wide temperature range.
Particular Gravity: The ratio of bitumen density to water density is known as specific gravity. Typically, the specific gravity of bitumen 60/70 falls between 1.01 and 1.05. This characteristic assists in quality control and estimating the bitumen required for a particular application.
Bitumen 60/70 should be 99.5% or more solubilized in trichloroethylene, at the very least. This test guarantees that the bitumen is free of pollutants and impurities, which might compromise its performance.

The minimal temperature at which bitumen 60/70 may catch fire when exposed to an open flame is known as its flash point. For safety purposes, this criterion is crucial. Bitumen 60/70 is generally safe to handle and transport since it has a flash point of around 225 degrees Celsius.
Thin-Film Oven Test (TFOT): The TFOT test is carried out to ascertain the bitumen's aging characteristics. The TFOT standards, which include certain changes in penetration and softening point following the test, should be met by bitumen 60/70. This guarantees that the bitumen won't significantly degrade even after prolonged exposure to the elements.
Breaking point: The lowest temperature at which bitumen becomes brittle and fractures when bent, is known as the Fraass breaking point. This breaking threshold for bitumen 60/70 is approximately -22 degrees Celsius. It is crucial to evaluate how well bitumen performs in cold weather.
Performance Grade: Bitumen 60/70 is often categorized using the Performance Grade (PG) system, which explains whether it is suitable for various temperatures and environmental factors. The usual PG grade for bitumen 60/70 is PG 64-22, showing the material's qualities with regard to temperature and penetration.
