PAS 2161 road condition categorization

The condition categories use a scale of 1 to 5. Each category indicates the type of maintenance treatment that an engineer considers necessary to restore a section of road to a ‘good’ condition. A ‘good’ condition is a condition not requiring any further maintenance.

Condition categories and potential maintenance options
Category Description Potential maintenance treatment option
1 No deterioration Pavement is not considered for maintenance
2 Minor (and/or aesthetic) deterioration Light maintenance, for example, minor patching
3 Moderate deterioration Localized intervention or mid-life preventative maintenance, for example, surface dressing, patching, or crack sealing
4 Moderate to severe deterioration Rehabilitative maintenance, possibly full carriageway. For example, resurfacing with thin overlay, surface dressing and multiple patching, or edge haunching
5 Severe deterioration Structural maintenance, for example, full carriageway resurfacing or reconstruction
