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.
