When contractors ask for a binder that performs well in cold climates, resists cracking, and still handles heavy traffic loads, Bitumen AH 130 is often the answer. This Chinese grade AH 130 is a high-penetration paving bitumen designed for flexibility, durability, and smooth asphalt mixing performance. It is widely used in road construction, highway base layers, airport pavements, and municipal infrastructure where low-temperature cracking must be minimized. If you are looking for a reliable Bitumen AH 130 supplier, this grade offers a balanced solution between softness and structural stability.
Bitumen AH 130 is a high-penetration asphalt binder produced under Chinese standards for road construction. The “130” refers to its penetration value range (0.1 mm units at 25°C), meaning it is softer than AH 90 and AH 70 grades.
Because of this higher penetration range, AH 130 offers:
Excellent flexibility in cold weather
Reduced risk of thermal cracking
Good adhesion with aggregates
Easy pumping and mixing during production
In practical terms, this grade is often selected for regions with colder winters or where pavement movement is expected.
Chinese grade AH 130 is primarily used in:
Highway pavement layers
Municipal roads
Airport runway sublayers
Bridge deck asphalt layers
Industrial yards
In colder regions, rigid binders can lead to cracks over time. AH 130 reduces this risk by allowing slight flexibility under temperature changes and traffic pressure.
Compared to standard penetration bitumen, AH 130 belongs to the softer end of the penetration spectrum. This makes it ideal when pavement durability under thermal stress is a priority.
The main feature of AH 130 is its penetration range around 120–140 dmm. This indicates a softer consistency compared to AH 90 or AH 70.
It bonds well with crushed aggregates. This ensures:
Better load distribution
Reduced stripping
Improved pavement lifespan
3. Workability During Mixing
AH 130 flows smoothly at mixing temperatures. Contractors appreciate its ease of pumping and blending during hot mix production.
Although softer, it maintains structural stability at service temperatures when properly designed in the mix.
| Grade | Penetration Range | Main Use |
|---|---|---|
| AH 70 | Harder | Hot climate highways |
| AH 90 | Medium | General road construction |
| AH 110 | Moderately soft | Cold regions |
| AH 130 | Soft | Cold climates & flexible pavements |
If your project is in a region with freezing winters, AH 130 often outperforms harder grades in crack resistance.
High-quality Chinese grade AH 130 is produced from vacuum bottom residue through controlled air blowing and refining processes. During production:
Temperature control is strictly monitored
Penetration tests are conducted batch by batch
Softening point is verified
Ductility is tested to ensure flexibility
A professional Bitumen AH 130 supplier provides:
COA (Certificate of Analysis)
TDS (Technical Data Sheet)
Independent inspection upon request
ATDM supplies AH 130 with full documentation, ensuring buyers receive consistent quality for road and infrastructure projects.
Bitumen AH 130 can be supplied in:
180 kg new steel drums
150 kg drums
Jumbo bags
Bulk shipments
Bitutainers
Packaging depends on your destination, project scale, and unloading facilities.
For export markets, drum quality and sealing are critical to prevent leakage and oxidation during transport.
Proper handling improves performance and safety:
Store in dry, covered areas
Avoid prolonged overheating
Maintain recommended heating temperatures
Prevent water contamination
Because this material is used for asphalt production, temperature management during storage tanks is essential for maintaining its original properties.
Demand for AH 130 depends on:
Road construction activity
Seasonal infrastructure projects
Crude oil fluctuations
Regional pavement standards
Like all paving binders, bitumen price changes according to crude oil trends, refinery capacity, and logistics costs.
When planning procurement, long-term contracts can protect buyers from short-term market volatility.
Choosing the right supplier matters more than many buyers realize.
A professional supplier offers:
Consistent penetration range
Verified softening point
Stable ductility performance
Reliable loading schedules
Clear export documentation
ATDM works with approved refineries to supply Chinese grade AH 130 under strict quality control. For large infrastructure projects, consistency between shipments is essential.
In hot mix asphalt production, AH 130 performs well due to its flexibility and bonding properties.
When blended with aggregates:
It coats evenly
Reduces micro-cracking
Improves fatigue resistance
Extends pavement service life
In regions where seasonal temperature differences are high, this grade supports long-term pavement stability.
Engineers often compare AH 130 with traditional asphalt binders to select the best solution for their specific climate and traffic conditions.
If you import Chinese grade AH 130, consider:
Port loading capacity
Shipping time
Drum quality
Documentation accuracy
Customs requirements
Working with an experienced Bitumen AH 130 supplier simplifies export procedures and reduces risk of delays.
ATDM supplies this grade for international road projects, ensuring proper packaging and inspection before shipment.
Longer-lasting roads reduce maintenance frequency. When pavement cracks less, repair costs decrease. This indirectly supports sustainability goals in infrastructure planning.
Because AH 130 is flexible, it can reduce premature cracking, especially in areas with freeze-thaw cycles.
Is Bitumen AH 130 suitable for hot climates?
It can be used, but harder grades like AH 70 may perform better in extreme heat.
Is Chinese grade AH 130 equivalent to penetration 120/150?
It is similar in softness, but specifications depend on refinery standards.
Can it be used for airport projects?
Yes, especially in sublayers and colder regions.
How is it tested?
Penetration, softening point, ductility, flash point, and solubility are standard laboratory tests.
