The bitumen 60/70 with penetration value measured at 25 degrees Celsius, plays a crucial role in road construction. This specific grade is commonly used as an asphalt binder, creating a strong adhesive layer between the base and aggregates. Bitumen 60/70 exhibits exceptional binding capabilities, ensuring a robust bond between aggregates for the production of high-quality asphalt, paving materials, and waterproofing agents.
Additionally, its flexibility allows for expansion and contraction of the pavement due to temperature changes. Furthermore, it provides durability and resistance to water, making it suitable for various weather conditions.
Differences of 60/70 and bitumen 80/100
Standard bitumen 60/70 has penetration between 60 to 70, whereas bitumen 80/100 has penetration between 80 to 100. Additionally, the softening point of 60/70 is 48 to 52, while that of 80/100 is 42 to 48C.
Usage of bitumen 60/70
1. Road Construction
Firstly, paving grade bitumen 60/70 is extensively utilized as a binder in the construction of roads and highways. In addition to serving as a binder, it contributes significantly to enhancing the durability and strength of the road surface.
2. Asphalt Mixtures
Moreover, it is a key component in the production of asphalt mixtures or hot mix asphalt (HMA), which is used for surfacing roads, parking lots, and other paved areas.
3. Roofing
Furthermore, it is also employed in the manufacturing of roofing materials, such as asphalt shingles and roofing felt and membrane roll sheet. Moreover, its waterproofing properties make it suitable for protecting buildings from water damage.
4. Waterproofing
Additionally, due to its water-resistant properties, it is used in the production of waterproofing materials for various applications, including foundations and basements.
5. Pavement Sealants
Furthermore, it is used in pavement sealants and coatings to effect the durability and longevity of paved surfaces.
6. Industrial Applications
Lastly, it is used in various industrial applications, such as corrosion protection for pipes and tanks.
Why you get different price of bitumen 60/70 from different suppliers?
Generally Bitumen has different quality, and it is raw material for other grades of bitumen like PMB and emulsion bitumen. So quality of this product depends on bitumen 60/70. Public refineries always have the highest prices, and then private refineries, followed by packing factories. Therefore some suppliers make the bitumen with vacuum bottom (VB), which is expensive. Meanwhile, others use a blend of VB and vacuum resin (VR), and some opt for cheap VR, which does not meet all the standard indices, resulting in a lower price.
Embossed bitumen means
High brands public refineries make the bitumen and emboss the drums therefore signifying that it is filled up inside of the bitumen refinery, and the quality is guaranteed by their name. Meanwhile, the quality of private refineries is very good, but it depends on the vacuum bottom, resulting in finished products with different outcomes not only in basic items but also in other technical specifications like viscosity at 60C and 130C. Public bitumen manufacturers have a higher cost, so their prices are consequently higher than those of others.
How to Buy High-Quality Bitumen 60/70?
Assessing the quality of bitumen involves various controls. However, after confirming the penetration value, a simple test can help determine its quality:
Odor: A lesser smell indicates lower sulfur content, as some may add sulfur to increase weight.
Viscosity: Ensure the viscosity falls within the specified range. Using vacuum resin instead of vacuum bottom can affect quality.
Spot Test: It should yield a negative result, as some factories heat bitumen directly, leading to burning.
Choosing a Bitumen Factory
There are four types of bitumen factories, each with varying investment costs and quality:
Continuous Production: Offers the highest quality but comes at a higher price.
Batching Type with Hot Oil Circulation Heating: May not pass TFOT test.
Batching Factory with Direct Heating: Prone to burning and molecular chain changes.
Blending Type: Has problems with viscosity and high wax content, making it challenging to use in asphalt.

Ductility of Bitumen 60/70
Sulfur, ranging from 3-7% by weight, can be added to hot-mixed asphalt to enhance ductility at low temperatures. Small amounts of rubber are another option to further increase ductility. Additionally, extender oil is recommended, and it is available in various viscosities, such as 10, 20, and 30-40.
Viscosity of Bitumen 60/70
The viscosity 60/70 falls within the range of 1600 to 2400. It measures the resistance to flow, affecting deformation resistance. Moreover, wax content directly impacts viscosity, making lower wax content preferable for easier asphalt work.
Specific gravity of bitumen
At 25C the Specific Gravity Kg/Cm3. is 1.01 to 1.06 which is refers to the ratio of the density of a substance to the density of a reference substance (usually water) therefore In the context of 60/70, it provides insights into the density and compactness of the bitumen material.
Fire point of bitumen (flash point)
The fire point of Bitumen 60/70 is minimum 220C and refers to the temperature at which the material emits vapors that can sustain combustion in the presence of an external ignition source therefore it is a crucial parameter for evaluating the flammability and fire resistance of bitumen-based products.
