12 100m/20m sections with urgency class 100m/20m sections

13 Automatic generation of maintenance sections Maintenance sections

14 Visualization of maintenance sections on maps

15 Visualization on road profiles

16 Visualization with online expert-system IT-ZEB-Server

17 Activates a list for the selection of a region category Activates a filter for the selection of regions Thematic map; coloration of regions depends on the class of the selected indicator Table with indicator values for each region (State Building Offices) Activates a list for the selection of an indicator Explanation text relating to the selected indicator Legend with coloration for each class of the selected indicator Checkboxes for the activation or the deactivation of layers Frequency distribution for classes of the selected indicator Visualization of Key Performance Indicators Bar graph; size of bars is proportional to the value of the selected indicator Time series for the selected indicator Switch between time periods of pavement diagnostic

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