| AWM Table: | Carriageway |
| Attribute: | Network Type |
| Purpose: | To provide road categorisation that differentiates the current level of service provided by the road section (carriageway). This closely aligns to accessibility, the type of vehicle that can be used and comfort experience of the road users. |
| Value | Description | Photo Example |
|---|---|---|
| Sealed Road | A sealed road is one which has been formed to a recongnised construction standard using surface treatments such as tar, bitumen, concrete or asphalt. Therefore it has been permanently “sealed”. This provides a 'waterproof' cover for the pavement beneath. |   |
| Unsealed Road | An unsealed road is one which a pavement has been formed and constructued with some type of compacted basecourse material and to a standard that ideally allows all year round access by all vehicle types. |  |
| Track | A track is a road that has limited or no constructed pavement and may have had some metal applied as a surface layer but not as a pavement with any depth. |  |
| Proposed Road | A road that has not been formed, but has been proposed to be built in the future. | Not Applicable |
Deteriating Conditions
Note: a sealed road may revert to an unsealed road if the sealed surface is not maintained and / or renewed, to the point where there is effectively no surface remaining for the majority of the road section.
Note: an unsealed road may revert to a Track if the pavement is not maintained and / or topped up, to the point where there is effectively no pavement remaining for the majority of the road section.
The above scenarios are not when there is a backlog of maintenance but rather a decision to let the road revert to unsealed or a track.
