Table 2
Condition level description for field evaluation.
| Condition level | Description |
| Good | Good condition, no inspected damage on the interlayer |
| Minor | Minor damage: interface of cement concrete shows scaling Cement concrete aggregates are exposed |
| Severe | Deterioration depth is greater than 25 mm Aggregates are removed from the surface Traces of moisture are remarkable |
| Heaved | Asphalt concrete is heaved and completely detached from the cement concrete |
