Bitumen 90-130 is a penetration-grade asphalt binder prized for its balance of flexibility and strength. Contractors choose it for road pavements, waterproofing, and many industrial tasks because it performs reliably in moderate to cool climates.
Understanding the Penetration Grade
The “90-130” tag refers to a penetration range of 90 to 130 decimillimetres at 25 °C. In simple terms, a standard needle penetrates this bitumen between 9 mm and 13 mm under a 100 g load in five seconds. Lower numbers mean harder bitumen; higher numbers mean softer, more elastic material. Bitumen 90-130 offers an ideal middle ground for surfaces that need resilience and crack resistance.
How Bitumen 90-130 Is Manufactured
Producers refine vacuum bottom residues from crude oil in distillation columns and then air-blow the residue to reach the target penetration. Tight process control guarantees that Bitumen 90-130 meets ASTM D5, AASHTO T49, and EN 12591 standards without fail.
Key Physical Properties of Bitumen 90-130
| Property | Typical Value | Test Method |
|---|---|---|
| Penetration @ 25 °C | 90 – 130 dmm | ASTM D 5 |
| Softening Point | 42 – 50 °C | ASTM D 36 |
| Ductility @ 25 °C | > 100 cm | ASTM D 113 |
| Flash Point | > 230 °C | ASTM D 92 |
| Specific Gravity @ 25 °C | 1.01 – 1.05 | ASTM D 70 |
Softening Point Significance
A softening point around 45 °C ensures Bitumen 90-130 remains solid during transport yet softens enough under paving temperatures for excellent workability.
Viscosity and Mix Design Advantages
Because of its moderate viscosity, Bitumen 90-130 blends smoothly with aggregates. Therefore, asphalt plants can lower mixing temperatures, saving fuel and reducing emissions.
Adhesion and Cohesion Benefits
Strong adhesive bonds anchor aggregates firmly, while cohesive strength resists rutting. Consequently, pavements enjoy longer service life and fewer maintenance cycles.
Weather Resistance and Durability
In colder regions, pavements face thermal stress. Bitumen 90-130 flexes instead of cracking, keeping water out and preventing costly freeze–thaw damage.
Bitumen 90-130 for Road Construction Applications
Base and binder courses in temperate climates
Low-traffic rural roads that need flexibility
Surface dressing where chip retention matters
Cold-patch asphalt mixes for all-season repairs
Industrial Waterproofing Uses
Bitumen 90-130 melts at moderate temperatures, coats substrates evenly, and cures into a seamless barrier. Therefore, engineers specify it for:
Tank-bottom linings
Pipe coatings
Expansion-joint fillers
Comparing Bitumen 90-130 vs. Bitumen 60-70
| Feature | 90-130 | 60-70 | Why It Matters |
|---|---|---|---|
| Penetration | Softer | Harder | 90-130 flexes more, ideal for cooler zones |
| Mixing Temp | Lower | Higher | Saves energy and limits aging |
| Crack Resistance | Higher | Lower | Less thermal cracking risk |
Handling and Storage Best Practices
Heat gradually: Raise temperature in 10 °C increments to avoid foaming.
Maintain 150-165 °C while pumping: This range keeps viscosity optimal without excessive aging.
Use insulated tanks: They stabilize heat and prevent oxidation.
Follow PPE rules: Heat-resistant gloves, goggles, and face shields protect crews from splashes.
HS Code and Regulatory Compliance
Most customs offices use HS code 27132000 for Bitumen 90-130. Therefore, buyers need to check their local import licenses first. In addition, they should review REACH rules in the EU. Finally, they must follow all safety data sheet (SDS) requirements to stay compliant.
Packaging Options
| Format | Typical Weight | Ideal For |
|---|---|---|
| New steel drums | 180 kg | Small projects, remote sites |
| Jumbo bags | 1 tonne | Faster unloading, reduced waste |
| Bulk in bitu-containers | 25 tonnes | Large paving jobs, cost efficiency |
| ISO tankers | 25-26 tonnes | Long-haul exports, minimal contamination |
Quality Control and Testing
Reputable suppliers always test each batch in the lab to check penetration, softening point, ductility, and loss on heating. In addition, they follow ASTM D6 standards to make sure results stay reliable. Moreover, they include a certificate of analysis with every shipment. As a result, buyers feel confident about the quality and consistency of the product.
Environmental Considerations
Bitumen 90-130 is 100 % recyclable. Old pavements can be milled, reheated, and reincorporated into new asphalt—cutting landfill waste and conserving crude-oil resources. Moreover, lower mixing temperatures shrink CO₂ footprints.
Tips for Sourcing Bitumen 90-130
Verify refinery origin: Consistent feedstock means consistent quality.
Check penetration and softening certificates: They must align with project specs.
Request fresh drums: Rusty barrels contaminate product and add disposal headaches.
Compare delivered cost: Include inland haulage, port fees, and heating charges.
Consider seasonal demand: Prices rise before paving seasons; forward contracts lock in savings.
