| Carriageway | Previously patched surface resulting in numerous joints. | Where > 40% then consideration for surface treatment. | |
| Carriageway | Loss of Skid Resistance / texture over whole surface area. | Consideration for Surface Dressing or other proprietary treatment. | |
| Carriageway | Edge Deterioration | > 20% of length of carriageway edge patching required. > 50% of length then Edge Strengthen and or kerb. | |
| Carriageway | Wheel Track rutting | > 20mm deep over 10% of length then patch or local resurfaces. > 20mm deep over 90% of length of road then Reshape effected lane | |
| Footways (per 100m length) | |||
| All footways | Footways | Course cracking of the surface. Course crazing, depressions greater than 25mm | > 40 % of surface area then consideration for surface treatment |
