Restoring Australia’s reseal program to a minimum of 7 per cent of the network annually; the most cost-effective infrastructure investment available to government.

Australia’s road network supports a transport sector that generates $137.2 billion annually and carries 260 billion vehicle kilometres each year. Yet the national maintenance backlog now stands at approximately $13.6 billion, and across multiple jurisdictions, periodic resealing rates have declined below the level required to maintain network condition.
The consequences are measurable: accelerating pavement deterioration, expanding reactive repair costs, and a growing backlog of avoidable reconstruction.

This white paper sets out the case for restoring periodic resealing programs to industry benchmark; a minimum of 7 per cent of the sealed network resealed each year, supported by a consistent body of Australian and international research.

The benchmark measures network proportion, not budget ratio. A jurisdiction can spend heavily on reactive repairs while still resealing too little of its network to keep pace with surface ageing. The +7 per cent metric measures the one variable that determines whether the network’s surface age profile remains sustainable.

The +7 per cent commitment is fundable, deliverable, and measurable.
