2009 - EU - Estimating Road Maintenance Backlog

Maintenance backlog can be used as a common and comparable denominator of road maintenance results for different types of road sub-assets and for different management tasks. The objective of the project was to prepare recommendations for the comprehensive
implementation and use of maintenance backlog indicators (“best practice”).

The project covers the following sub-assets of the road infrastructure:

• Pavements (trafficked and non-trafficked areas)
• Engineering structures (bridges, tunnels, walls and other engineering structures)
• Road furniture (signs, guardrails, lights, etc.)
