Penetration grades
Grades such as 60/70 or 80/100 are usually evaluated by penetration at 25°C, softening point, ductility and related properties.
Bitumen specifications are the technical language of a serious bitumen transaction. The same grade name may not be enough unless the buyer also reviews the final test values, accepted standards and required documents.
This page gives importers and asphalt buyers a practical overview of the specification points they should discuss before requesting a final offer from Bitumen Asphaltive.
Grades such as 60/70 or 80/100 are usually evaluated by penetration at 25°C, softening point, ductility and related properties.
VG30 and VG40 focus on viscosity behavior and are commonly used where viscosity-based project specifications are required.
The final COA should match the agreed grade and be checked against the project’s accepted specification range.
The exact values depend on grade and source. Use this table to understand what each test means for buying decisions.
| Property | What it indicates | Common document | Buyer action |
|---|---|---|---|
| Penetration at 25°C | Relative hardness or softness of the binder | COA / TDS | Compare with project grade range |
| Softening point | Temperature at which bitumen begins to soften | COA / TDS | Check suitability for climate and application |
| Ductility | Ability to stretch before breaking | COA | Review for paving performance expectations |
| Viscosity | Resistance to flow at specified temperature | COA / TDS | Critical for VG30 and VG40 |
| Flash point | Safety indicator during heating | COA / MSDS if required | Review for storage and heating operations |
| Solubility | Purity/bitumen content indicator | COA | Verify against specification requirement |
A professional export inquiry is faster when the technical and commercial points are clear from the first message.
Share destination, product grade, quantity, packing method, delivery term and required timeline.
We match the request with suitable grade, typical specification range, packing and document requirements.
The offer is prepared around quantity, logistics route, availability, inspection needs and payment structure.
Before loading, the shipment file is checked for invoice, packing list, COA/TDS and destination documents.
For export supply, documentation is as important as product availability. The exact document set depends on product type, destination and delivery term.
Certificate of Analysis and Technical Data Sheet are used to confirm product quality, test values and grade consistency for every serious inquiry.
Depending on the delivery route, documents may include commercial invoice, packing list, bill of lading draft, origin documents and inspection notes.
We avoid unclear offers. Buyer identity, destination, product use and document requirements are reviewed before commercial commitment.
All RFQs are handled through the official Iran WhatsApp number so the discussion remains fast, traceable and focused on the shipment file.
Use these pages to compare grades, packaging methods, regional supply routes and documentation requirements before sending your inquiry.
No. Website specification tables are buyer guides. Final values must be confirmed by the official TDS, COA and contract terms.
Penetration grades classify bitumen mainly by needle penetration, while VG grades classify by viscosity behavior.
Yes. Sending the project specification helps match the correct grade and avoid misunderstanding.
The COA is the main final quality document, while the TDS explains typical grade properties and technical positioning.
Send your required grade and project specification on WhatsApp so the technical discussion can be aligned before any offer.
