Bitumen or Asphalt usually in two forms:
Liquid bitumen at temperature above 100 degrees C: This type is often transported by specialized ship tanker and pumped to a dedicated shore tank with heating system …
Asphalt solidifies at normal temperature: This type is usually packed in drums, then packed into containers for transport.
Inspection scope of bitumen as below:
Liquid bitumen at temperatures above 100 degrees C:
- Ship arrival quantity inspection
- Ship’s discharged/loaded quantity inspection
- Ship’s discharged/loaded quantity inspection (applied VEF)
- Discharging/Loading supervision
- Ship’s ROB inspection by Wedge calculation
- Quality inspection (sampling and sample analysis)
- Shore receipt inspection/Shore tanks inspection
- …
Asphalt solidifies at normal temperature in drums/container
- Quantity inspection by tally count number of drum
- Weight inspection by weighscale (drum by drum weightment or container weightment)
- Condition inspection, stuffing, stowage
- Quality inspection (sampling and sample analysis)
- …
The analysis parameters for asphalt samples are as follows:
| No.: | Testing items | Unit | Testing method |
| 1 | Penetration at 25oC, 0.1mm, 5s | 0,1mm | ASTM or TCVN |
| 2 | Penetration Index (PI) | ||
| 3 | Softening Point (R&B method) | oC | |
| 4 | Dynamic viscosity at 60oC | Pa.s | |
| 5 | Ductility at 25oC, 5cm/min | cm | |
| 6 | Wax Paraffin Content | % | |
| 7 | Flash Point (Cleveland Open Cup) | oC | |
| 8 | Solubility in Trichloroethylenen | % | |
| 9 | Specific Gravity | g/cm3 | |
| 10 | Thin Film Oven Testing (TFOT) | ||
| Change of Mass | % | ||
| Retained Penetration, % of Original | % | ||
| Ductility at 25oC, 5cm/min | cm | ||
| 11 | Coating Criteria (Boiling Method) | Level |
