Pavement Management Strategic Plan

Our Pavement Management Strategic Plan helps us make the best maintenance and renewal decisions and prioritise available funding.

Figure 1 - Cross Section of Road PavementBackground

We manage approximately 23,000 kilometres of arterial road network across Victoria, which is worth over $20 billion.

Ongoing and regular maintenance work is required to preserve the safety and condition of road pavement.

Road pavements consist of two layers; the surface layer which has a lifespan of 10-15 years and the structural layer which has a lifespan of over 40 years.


We undertake three types of pavement preservation works:
  • Routine maintenance - inspecting and fixing of isolated defects and hazards.
  • Resurfacing - replacing the surface layers to protect the pavement from water damage and correcting surface defects.
  • Rehabilitation - rebuilding a failed pavement to restore the structural and surface layers to an “as new” condition.
The physical characteristics to define poor road condition are:
  • roughness
  • rutting
  • cracking
  • extent of patching
  • texture loss
  • loss of aggregate (the small stones which make up the road’s surface).

The images below are examples of poor road conditions.

Why do we have a pavement management strategic plan?

The way we use the road network has changed significantly since most of it was built in the late 1940s and 50s, when the largest vehicle expected on the network was approximately 40 tonnes and we had far fewer vehicles on our road network.

Victoria's rapid population growth is increasing by more than 2% annually and we’re adding an extra 2,000 new cars on the road network every week. In addition, a shift to a service based economy has resulted in an increase of trucks and other commercial vehicles on our roads.

The Pavement Management Strategic Plan sees us invest in the most important roads at the right time, and ensure we’re looking ahead to what the community will need in the foreseeable future.

How the Pavement Management Strategic Plan is used?

Our Pavement Management Strategic Plan has expanded the focus from planning and measuring the work we do, to focus more on community outcomes. Specifically this means investment in roads that contribute to the Victorian economy; safety, wellbeing and journey experience.  

The strategic plan outlines our investment decision making criteria that are summarised in Figure 6.

Critical Works

Reactive works to restore road conditions that have resulted in speed reductions, a significant negative impact on productivity or road safety.Reactive works to restore road conditions that have resulted in speed reductions, a significant negative impact on productivity or road safety.

 

Needed Works

Proactive works to prevent road conditions being compromised in the short term (next 12-24 months).Proactive works to prevent road conditions being compromised in the short term (next 12-24 months).

 

Desired Works

How does the strategic plan work?

Maintenance and renewal investment will be prioritised based on the road classification and the type of work that is required. The table below outlines our funding priorities

 

Figure 7 - Asset Renewal Funding PrioritiesWhy is Needed Works on Class 2 road funded before Critical Works on a Class 4 road? Prioritising a high class road will provide more benefit to the community (safety, productivity and journey experience) from the money invested.
