The purpose of the sealed road network is to provide effective movement of goods, produce and people, across a safe suitable all-weather surface. Satisfying the expectations for a consistent, accessible and safe sealed road network within limited funding requires careful prioritisation of sealed road activities.
Council has 1187 kilometres of sealed road supporting a large geographic area. The vast majority of sealed roads are rural with relatively low traffic volumes, primarily consisting of traffic such as logging trucks, stock trucks and milk tankers. An increase in logging across the district in future years will result in an increased deterioration of the rural network, with the effects of this yet to be fully determined.
Important activities include:
- Network inspections; identification, assessment and recording of road defect information to enable robust maintenance programming.
- Cyclic patrols; remedying minor road defects such as potholes on a cyclic basis, where the road’s patrol frequency is based on its classification (or function and use), to ensure a safe level of service is being provided.
- Programmed maintenance; programmed repair of road defects such as pavement deformation and surface cracking in an effective and efficient manner to ensure the asset is maintained in a safe and serviceable condition, while maximising its life and realising the investment made in it.
- Pavement resurfacing; renewal of the road’s surface to maximise the life of the underlying, more expensive pavement and to restore skid resistance.
- Pavement rehabilitation; renewal of the entire road at the end of its useful life to restore and/or increase pavement strength, minimising increasing and ongoing maintenance costs.
- Minor improvements; generally carried out in conjunction with the pavement rehabilitation to improve safety, such as widening, realignment, and sight distance improvements.
