Bitumen Grade 85/25
Last updated: 2026-09-30
Bitumen grade 85/25 is a penetration-grade bitumen with a needle penetration of 85 dmm at 25°C and a softening point of 43–51°C. It is widely specified for hot-mix asphalt in warm to hot climates, road surfacing, and industrial waterproofing. In bulk export markets, 85/25 typically trades between $420 and $520 per metric ton FOB, depending on origin and crude slate.
What Is Bitumen Grade 85/25?
Bitumen 85/25 is classified under the penetration grading system (ASTM D946 / EN 12591), where the first number (85) is the penetration depth in tenths of a millimeter at 25°C, and the second number (25) refers to the typical low-temperature or viscosity-related parameter depending on the standard referenced. Its softening point sits between 43°C and 51°C, and it delivers a flash point above 250°C.
It sits in the middle of the penetration scale — softer than 60/70, harder than 100/120. That makes it a practical choice for:
- Warm-climate road construction where rutting resistance matters
- Hot-mix asphalt (HMA) for base and binder courses
- Industrial waterproofing and roofing membranes
- Cutback and emulsion manufacturing as a base stock
Unlike polymer-modified bitumen (PMB), 85/25 is unmodified and relies on crude source quality and refining precision for its consistency.
Bitumen 85/25 Specifications & Test Data
The table below summarizes the most commonly requested technical parameters for export-grade 85/25. Values reflect typical Gulf and Asian refinery output tested to ASTM D946.
| Property | Test Method | Unit | Typical Value | Spec Range |
|---|---|---|---|---|
| Penetration @ 25°C | ASTM D5 | dmm | 85 | 80–90 |
| Softening Point | ASTM D36 | °C | 47 | 43–51 |
| Flash Point (COC) | ASTM D92 | °C | 270 | Min 250 |
| Viscosity @ 135°C | ASTM D4402 | cP | 320 | 250–400 |
| Ductility @ 25°C | ASTM D113 | cm | 120 | Min 100 |
| Solubility in TCE | ASTM D2042 | % | 99.5 | Min 99.0 |
| Specific Gravity @ 25°C | ASTM D70 | – | 1.03 | 1.00–1.06 |
| Loss on Heating | ASTM D6 | % | 0.15 | Max 0.5 |
| Penetration after heating | ASTM D5 | % | 72 | Min 65 |
For buyers, the two number that decide acceptance or rejection are penetration (80–90 dmm) and softening point (43–51°C). Everything else is a support parameter that confirms thermal stability and purity.
Bitumen 85/25 vs 60/70 vs 100/120: Comparison Table
Buyers frequently compare 85/25 against the two most common alternative grades. The differences below matter for climate selection and cost.
| Parameter | Bitumen 60/70 | Bitumen 85/25 | Bitumen 100/120 |
|---|---|---|---|
| Penetration @ 25°C (dmm) | 60–70 | 80–90 | 100–120 |
| Softening Point (°C) | 49–56 | 43–51 | 40–47 |
| Climate Suitability | Hot / heavy traffic | Warm to hot | Moderate / cold |
| Rutting Resistance | High | Medium-High | Medium |
| Flexibility at Low Temp | Lower | Moderate | Higher |
| Typical FOB Price (USD/MT) | 430–530 | 420–520 | 410–500 |
| Common Uses | Highways, airports | Roads, waterproofing | Cold-climate paving |
Key takeaway: 85/25 offers a middle ground — more workable than 60/70 in ambient temperatures above 30°C, yet harder and more rut-resistant than 100/120.
Pricing, Packaging & Logistics Data
Export pricing for bitumen 85/25 is driven by crude benchmark spreads, freight, and packaging format. Below is a snapshot of typical 2024–2025 export economics.
| Cost Component | Typical Value | Notes |
|---|---|---|
| Base FOB price | $420–$520 / MT | Varies by origin (UAE, Iran, Singapore) |
| New steel drum (150 kg) | $95–$130 / MT premium | 5.8 drums per MT approx. |
| Polybag (25–50 kg) | $110–$145 / MT premium | Higher handling, lower volume per unit |
| Bulk vessel (ISO tank) | $380–$470 / MT | Min 20 MT per ISO tank |
| Freight (Gulf → Asia) | $25–$45 / MT | 20-ft container, 10–15 days transit |
| Freight (Gulf → Africa) | $55–$90 / MT | Higher port congestion surcharges |
| Payment terms | LC at sight / TT 30% advance | Standard export terms |
Packaging options for 85/25:
- New steel drums — 150 kg or 180 kg net, standard for containerized export
- Polybags — 25 kg, 35 kg, 50 kg; suited to small distributors and retail
- Jumbo bags (FIBC) — 1 MT with heat-resistant liner
- ISO tanks / bulk vessel — for volume buyers above 500 MT
- Bitutank (flexitank) — 20 MT per 20-ft container, cost-efficient for mid-volume
Typical order tonnage and lead times:
| Order Size | Packaging | Lead Time |
|---|---|---|
| 20–100 MT | Drums / bags | 7–14 days |
| 100–500 MT | Drums / flexitank | 14–21 days |
| 500–5,000 MT | Bulk vessel | 21–35 days |
How to Source Bitumen 85/25: Quality Checks & Red Flags
Because 85/25 is often re-labeled or blended, verifying quality before shipment is critical. Use this checklist:
- Request a pre-shipment COA (Certificate of Analysis) from an accredited lab — not just a mill certificate
- Confirm penetration and softening point from an independent third-party inspector (SGS, Intertek, Bureau Veritas)
- Check flash point minimum of 250°C — anything lower signals contamination with lighter fractions
- Verify solubility ≥ 99% — low solubility indicates filler or polymer adulteration
- Inspect drum markings — batch number, net weight, and production date should match the COA
- Compare price against market range — quotes below $380/MT FOB are almost always off-spec or diluted
Common red flags in the 85/25 trade:
- Softening point reported above 55°C (likely blended with 60/70)
- Penetration stated as a single number rather than a range
- No third-party inspection offered
- Payment requested entirely by irreversible TT with no LC option
- Origin documents that don't match shipping route

Producers in the UAE, Iran, and Singapore dominate export supply of 85/25, while demand growth is strongest in India, Nigeria, Kenya, and Bangladesh.
Frequently Asked Questions
What is the difference between bitumen 85/25 and 60/70?
Bitumen 85/25 has higher penetration (80–90 dmm) and a lower softening point (43–51°C) than 60/70 (60–70 dmm, 49–56°C). This makes 85/25 softer and more workable in warm climates, while 60/70 is harder and more rut-resistant under heavy traffic.
What is the typical price of bitumen grade 85/25?
Export prices for 85/25 generally range from $420 to $520 per metric ton FOB, depending on origin, packaging, and order volume. Drummed product typically carries a $95–$130/MT premium over bulk.
What is the softening point of bitumen 85/25?
The softening point of 85/25 falls between 43°C and 51°C when tested to ASTM D36. This range makes it suitable for hot climates but less ideal for cold-region paving where 100/120 or 160/220 grades are preferred.
How is bitumen 85/25 packaged for export?
Standard export packaging includes 150 kg or 180 kg new steel drums, 25–50 kg polybags, 1 MT jumbo bags, and 20 MT flexitanks inside 20-ft containers. Bulk vessel shipment is used for orders above 500 MT.
Which countries produce bitumen grade 85/25?
Major producers include the UAE, Iran, Singapore, and Bahrain, with additional supply from South Korea and India. Buyers should always verify origin documents and independent lab test reports before confirming shipment.
