4.4 Validation
In the past 5 years a significant number of roads have been constructed on basis of the
PowerCem Technology. Parts of these roads are included in the model to give an impression of
the costs saved already. In figure 4.12 the roads already constructed on basis of the PowerCem
technology are shown in yellow.
Figure 4.12: Flood extents versus Roads with PowerCem(yellow)
To get an impression of the saving in the reference period of 28-06-2011 to 07-05-2012, the
total maintenance costs are determined, assuming that all the flooded roads were also
damaged. Next to the total costs the avoided maintenance costs are determined. The avoided
maintenance costs are in this case the roads constructed with the PowerCem technology. The
results are shown in table 4.6.
