Bitumen Paving Grades: 60/70 and 80/100 Specs & Logistics
Last updated:
Bitumen is the critical engineered binder for the global transport infrastructure. Sourced from refined heavy crude oil, WorldwideTradeX supplies high-purity penetration grade bitumen for road paving, airfield runways, and waterproofing applications across the EU, Africa, and the Middle East. Send the grade you need, the tonnage per shipment and the discharge port, and we will quote penetration-grade bitumen in a request a quote.

1. Grade Selection: Climate-Responsive Paving
The "Penetration Grade" refers to the hardness of the bitumen at 25°C.
- 60/70 Grade: The industrial standard for temperate to hot climates (e.g., Middle East, Africa, Southern Europe). Its balanced viscosity prevent rutting during high summer temperatures.
- 80/100 Grade: A softer grade preferred for colder or arctic climates (e.g., Eastern Europe, Nordic regions) to prevent asphalt cracking during winter freeze-thaw cycles.
2. Global Sourcing & Quality Standards
Quality is verified by the softening point and ductility metrics.
- Oxidation Control: Pure vacuum-distilled bitumen ensures minimal aging during the asphalt mixing process.
- Verification: Every batch is certified by SGS or Bureau Veritas to meet ASTM D946 or EN 12591 standards.
3. High-Efficiency Bitumen Logistics
- New Steel Drums: Typically 150kg or 180kg net weight. Ideal for remote infrastructure sites with limited storage.
- Bitutainers: 20ft mobile heated tanks (20-25 MT). Essential for large-scale highway projects where liquid bitumen must be kept at temperature.
- Sack Packaging: Meltable poly-bags (1 MT jumbo bags) for optimized freight costs.

Frequently Asked Questions
What is bitumen penetration grade and how is it selected for road construction?
Bitumen penetration grade (e.g., 60/70, 80/100) measures the depth (in 0.1mm units) a standard needle penetrates the bitumen under defined conditions. Lower numbers mean harder bitumen. 60/70 is used in hot climates; 80/100 in moderate climates. Selection depends on traffic load and ambient temperature range.What is the difference between bitumen 60/70 and VG-30?
60/70 is a penetration-graded bitumen; VG-30 (Viscosity Grade 30) is a viscosity-graded equivalent used in India and some Asian markets. VG-30 corresponds approximately to 60/70 penetration grade. The grading system differs but the physical properties are similar for road paving applications.How is bitumen transported in bulk international trade?
Bitumen is transported in heated tanker vessels (maintaining 150–170°C to keep it liquid), bitumen drums (180 kg), or jumbo bags for oxidized/blown grades. Bulk tanker shipments are most cost-efficient for volumes above 1,000 MT. Loading and discharge require heated infrastructure at both ports.What are standard quality tests for export-grade bitumen?
Key tests: penetration (ASTM D5), softening point (ASTM D36), ductility (ASTM D113), flash point (ASTM D92), and solubility (ASTM D2042). SGS or equivalent testing at loading terminal is standard. Certificate of Quality accompanies every shipment.More Frequently Asked Questions
Do you supply materials only or full packages?Both — pure material supply and coordinated packages (stone, bitumen, fit-out, PMC/EPC scopes) depending on the project.
Which documents accompany shipments?
Invoice, packing list, mill/CoA certificates, origin documents and project-specific compliance files as required.
Can you support site delivery (DAP/DDP)?
Yes where the destination and scope allow; otherwise FOB/CIF to your nominated port is standard.
How is quality controlled?
Factory certificates plus optional third-party inspection (SGS/Intertek) before loading.
How do we request a project quote?
Share drawings/specs, quantities, location and target completion via RFQ.
Destination Handling: Heating & Unloading
Drummed and bulk bitumen impose different infrastructure demands at the receiving end:
- Drums must be decanted in a drum melter (typically 4-8 drums per hour) or cut manually — budget labour and reheat fuel; skinned drums leave a 2-4% residual heel.
- Bitutainers require shore power or a portable boiler to reheat to 120-140°C before discharge; plan 12-24 hours of reheating after ocean transit.
- Bulk heated vessels need a receiving terminal with heated lines and insulated tanks capable of holding 150-170°C; discharge completes in hours when the terminal is properly equipped.
Related Grades: Oxidized and Polymer-Modified
Beyond paving penetration grades, two specialty families appear in project bills of quantities:
- Oxidized (blown) bitumen (e.g., 85/25, 95/25): air-blown for higher softening points; used in roofing membranes, pipe coating and expansion joints. Ships in meltable poly bags or cartons without heated logistics.
- Polymer-modified bitumen (PMB): SBS-modified binders for high-traffic highways and airfields, cutting rutting and thermal cracking. Production close to the point of use is preferred because PMBs can degrade on extended storage.
Project Order Checklist
Before confirming a bitumen contract, verify:
- Grade against your mix design climate zone (60/70 versus 80/100).
- Packaging matched to site decanting capability (drums, bitutainers or bulk).
- Vessel and terminal heating specs aligned with your paving season laycan.
- Third-party inspection scope: penetration, softening point and solubility as a minimum at loadport.
- MSDS and drum marking compliant with destination import rules.
- Demurrage terms — heated vessels carry high daily rates; conservative laytime saves money.
