Rural Road Maintenance

Rural Roads
The following is an overview of how Council priorities roads for the allocation of funding for the delivery of maintenance works. The scope of work includes maintenance on bitumen and gravel roads, signage and other road furniture, bridges and other drainage structures. Further details are available in Council's Roads Asset Management Plan.

Road Hierarchy

The rural network is classified into the following categories:
  • Arterial Roads
  • Rural Collector Roads
  • Rural Access Roads
  • Unformed Roads

Inspections

Council adopts a systematic approach to management of road maintenance requirements, recording and prioritizing defects to enable programming, when the intervention level is reached.

Council collects defect reports from three sources:
  • Reports from the public through Customer Service;
  • Informal inspections; and
  • Formal inspections.
The industry standard for measuring the roughness of a road is called the international roughness index (IRI). It is a measure of the axle movements along the road. Refer to Council's Road Asset Management Plan for further details. 

Defects

Defects are divided into three priority levels as below:

Priority 1: Safety Legislative

These activities cover defects which constitute a safety problem to the road user and for which, the intervention level is reached without significant warning as opposed to usability defects which occur over a long period of time and can be planned for repair in advance of serious failure.

Response time is generally within a 24-hour period.

Priority 2: Preventative

Regular inspections will determine the interim maintenance requirements [e.g. pothole / pavement / furniture repair] in accordance with approved defect intervention levels.

The objective of maintenance activities on gravel Minor Local access roads is to maintain them in a trafficable condition in the majority of weather conditions and within budgetary constraints.

Priority 3: Usability/ Appearance

Regular inspections will determine the interim maintenance requirements [e.g. pothole / pavement / furniture repair] in accordance with approved defect intervention levels.

The objective of maintenance activities on gravel Minor Local access roads is to maintain them in a trafficable condition in the majority of weather conditions and within budgetary constraints.


Operational Road Classification

This takes into account traffic volumes generated by large areas of population, commercial ventures, through traffic and/or tourist attractions etc. Select the tabs below to view details of each classification type. 
  1. 199
  2. 150
  3. 125
  4. 100
  5. 75
  6. 30
  7. 10

Operational Class 199: 
Generally Arterial Roads
Routes carrying a main flow with many branches


Roads with a traffic count generally more than 150 vehicles/day and are generally bitumen sealed.
They are through roads which connect to significant destinations and carry a main flow with a significant number of feeder roads.
The running surface is generally 6.5 – 8.0 metres wide [including shoulders].
They should be formed and generally drained to meet Q2 to Q5 standard, however, significant rain events may cause temporary closure.

Levels of Service

Below describes the work which Council aims to provide within the scope of the maintenance budget. Service provision may not always meet the service aim or it may be greater, dependent on the condition of the asset, unusual traffic use, weather patterns and/or natural disasters. Further details are available in the Roads Asset Management Plan. 
  1. Class 199-100 Roads
  2. Class 75 Roads
  3. Class 30 Roads
  4. Class 10 Roads

Class 199-100 Roads:

The objective of maintenance activities on sealed Class 199 to 100 roads is to prolong the life of the pavement and running surface before re-construction becomes necessary. Reseals will be applied on a 12 year cycle [approximately]. Regular inspections will determine the interim maintenance requirements [e.g. pothole/pavement repair, furniture and slashing, etc] in accord with approved defect intervention levels.

The objective of maintenance activities on gravel Rural Arterial roads is to maintain them in a trafficable condition in all weather conditions and within budgetary constraints. Maintenance activities are scheduled in accordance with approved defect intervention levels.
