Best Practice - Unsealed Roads Maintenance –Road Hierarchy Categories

 

Current practice in unsealed road maintenance for road hierarchy categories is listed in order of annual maintenance cost ($/yr) from lowest to highest.  Also shown are the key variables affecting life cycle cost identified in pilot council testing. 

 

Care is to be taken in interpreting the best practice report, as there are many factors, which affect annual maintenance costs of unsealed roads including travel distance, weather and environmental conditions, availability and suitability of gravel materials and topography.
