4.2.6 City area
Figure 4.9: Area in city road network.
In an area where there is a dense network like in a city, the number of roads is large. This
means when a road is flooded or damaged, the distance to alternative routes in cities is not
far, or an area will be cut off from its environs for a relatively short a period. However in a city
a lot of economic activities take place and the direct costs are also important values to
consider. This will lead to indirect costs, and direct costs due to the large amount or roads.
By using PowerCem Technology, the indirect costs will be low. After the floods, the damage on
the road infrastructure is minimal. This is because after floods on these roads, there is no
damage, and the roads can immediately be opened for use.
With traditional construction the roads will be severely damaged and the reparation time can
take up to a few weeks, in which time the road cannot be used. In a city area this is not
desirable.
