What is Bitumen 40/60: Bitumen 40/60+ uses and advantages!
Bitumen is a dark, viscous material that engineers mostly use for insulation and asphalt construction. Various types of bitumen are selected based on their specific properties for use in different weather conditions. An important characteristic of bitumen is its permeability, which experts usually grade bitumen products by it. In this article of Iran E Trade, we will explain more about bitumen 40/60, its production process, traits and uses.
Bitumen 40/60
Despite its black and sticky appearance, bitumen exhibits distinct characteristics that categorize its products into different types. Among these features, bitumen’s degree of penetration plays a crucial role. Penetration degree directly influences the hardness and softness of bitumen. The penetration index indicates which bitumen product has more longevity and flexibility for different climates.
As a general rule, lower penetration corresponds to harder bitumen, while higher penetration results in softer bitumen. Penetration grade refers to the extent of bitumen permeability into the earth’s surfaces and layers. Bitumen 40/60, with a penetration grade of 4 to 6 mm in 5 seconds, falls on the stiffer end of the spectrum. Therefore, engineers usually use this type of bitumen for road paving, construction, and repairs in hot climate regions.
How is 40/60 bitumen produced?
The oxidation rate of the vacuum residue affects the permeability of bitumen. 40/60 bitumen has a penetration depth ranging from 40 to 60 mm and a softening point between 48 and 56 °C. This type of bitumen exhibits thermoplastic properties similar to synthetic resin materials. As a result, it becomes more rigid when heated and softer in cold weather.
Manufacturers produce pure bitumen from the distillation of crude oil during the aeration process of vacuum residue. Vacuum residue refers to the material deposited in the vacuum distillation tower. When exposed to air and the creation of cross-linking bonds between molecules, the vacuum residue transforms into a sticky black substance known as bitumen 40/60.

40/60 bitumen features and specifications
Various types of bitumen, such as bitumen 40/60, have undergone extensive tests following global standards. Their properties, including density at 25 °C (laboratory temperature), penetration grade, softening point, ductility, weight loss during heating, penetration degree after heating, flash point, and solubility in trichloroethylene, have all been meticulously documented.

What are the uses of 40/60 bitumen?
Bitumen 40/60 is a standard product that engineers mostly use in road construction and asphalt applications. Bitumen with this penetration grade exhibits thermoplastic properties, making it soft at high temperatures and hard at low temperatures. This temperature-viscosity relationship is critical for determining bitumen’s performance parameters such as adhesion, durability, and the suitable temperature for applying bitumen.
