What are the impacts of bitumen 60/70 density in construction and infrastructure projects? This question is important while selecting bitumen 60/70 for different applications. Understanding its density assists clients and companies in choosing the right product that fits to deliver best delivers results for their projects.
What is penetration bitumen 60/70?
Bitumen 60/70 commonly known as asphalt or tar, is a sticky black and highly viscous product of petroleum. Penetration bitumen 60/70 comes in liquid or semi-solid form. It is a product of crude oil refinement. The first gasoline cuts majorly, leaves behind bitumen.
The 60/70 grade refers to its penetration value, indicating how deeply a needle penetrates the material under set conditions. This range (60 to 70) signifies a medium-hard bitumen.
Kiapetro, as a well-known bitumen 60/70 supplier, makes sure that the produced bitumen is highly qualified for various needs.
Learn about the production nuances that affect physical properties in Bitumen 60/70 production and maintenance process, a key factor in understanding density variations.
Bitumen 60/70 properties and specifications
Properties and specifications indicate the quality of bitumen which are measured through various bitumen tests. Other than penetration and bitumen 60/70 density tests, bitumen 60/70 specifications include viscosity test, softening point, ductility, loss on heating, and flash point test.
Below, the specifications for Bitumen 60/70 are explained.
- Penetration Degree: It is measured in the lab to evaluate hardness and bitumen 60/70 density. A 100-gram needle is inserted for 5 seconds at 25°C, and the depth of penetration is recorded. Lower penetration means harder bitumen.
- Flash Point: It is the temperature at which bitumen ignites due to vapor emissions. This indicates the upper limit for safe heating.
- Viscosity: A measure of thickness. This means that more solid bitumen is less fluid. Viscosity decreases as temperature increases, as tested with a Sea Bolt Fiorel device.
- Ductility: The ability to stretch. A sample is elongated at 5 cm/min until it breaks, showing flexibility.
- Weight Loss: Measured by heating bitumen at 163°C for five hours, this indicates evaporation of oils and petroleum chemicals.
- Softening Point: The temperature at which bitumen changes from solid to liquid. Bitumen 60/70 softens between 50–70°C, with higher values offering better heat resistance.
- Solubility: Indicates purity by measuring the number of impurities left after dissolving bitumen in solvents like carbon disulfide.

What is the density of bitumen 60/70?
Viscosity and density are essential factors that impact the performance and use of Bitumen 60/70. This directly influences how it is transported, stored, and applied.
Bitumen 60/70 density is measured by determining the mass of a known volume of a substance. For bitumen, this is done by weighing a sample and measuring its volume using a pycnometer or similar device. The density is calculated by dividing the mass by the volume.
Understanding these characteristics helps engineers and contractors optimize their processes, ensuring the desired performance of asphalt applications.
The density of Bitumen 60/70, used in road construction and waterproofing, ranges from 1,000 to 1,050 kg/m³.
Higher-density bitumen offers better durability, crack resistance, and waterproofing, while lower-density bitumen is more prone to damage and less effective over time or with temperature changes.
For optimal performance, bitumen 60/70 density around 1,020 kg/m³ balances flexibility and stiffness, promoting strong asphalt mixtures and effective bonding with aggregates. It also offers improved resistance to oxidation, thermal cracking, and other forms of degradation.
Meeting the required bitumen 60/70 density standards is crucial for achieving desired results in road construction and waterproofing. However, Kiapetro controls bitumen 60/70 density to ensure the durability and reliability of infrastructure.
