ERAnet road: the trans-national research project "MAINTENANCE BACKLOG – ESTIMATION AND USE"

Project description

The maintenance of infrastructure assets has become the most important part in road management in many countries all over the world. Thus, these countries are using different systems and methods to justify the required infrastructure investments.

The purpose of the trans-national research project "maintenance backlog – estimation and use" is to help road owners and road managers to implement and/or further develop maintenance backlog indicators for different assets of the road infrastructure. 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 (see also "Description of Work" DoW).

The output and results of this project should encourage general use of maintenance backlog including benchmarking between different road administrations on the national as well as on the international level. The project covers the following components of the road infrastructure:

• pavements (trafficked and non-trafficked areas)

• structures (bridges, tunnels, walls, and other structures)

• road furniture (signs, guardrails, lights, etc.)

The objective of the project is to prepare recommendations for the comprehensive implementation and use of maintenance backlog indicators ("best practice"). Those shall be based on analysis of experience in studied countries, available recent research reports, and the experiences of the involved parties.
