Maintenance of paved roads is carried out to preserve and improve the pavement and reduce the deterioration  process. An adapted treatment will make the pavement last for a certain time interval before next treatment is necessary. Pavement managers deal with complex decisions when identifying lengths of their networks in need of maintenance and selection of the appropriate maintenance treatments.

Decades of road network monitoring and follow up projects have generated a huge volume of empirical data on pavement condition. To complement this information, several decades of research and development has accumulated a substantial volume of knowledge, models and tools that can use the information to assist in maintenance decisions. Even so, these support tools are not yet implemented to their full potential, and most tools do not address user expectations and new environmental impacts such as fuel consumption and emissions. This paper will demonstrate a tool to assist road authorities in optimising the maintenance of their road networks.
