 Coordinated Maintenance and Building Program is constantlybeing improved and developed further.
 Pavement asset management is regarded as an elementof a complex Asset Management. Guidelines for the asset
management are currently being developed.
 The Key Performance Indicators (KPIs) play an important role.
