Road design

PROBLEM

Roadway designs are subjected to significant climatic influences. In northern climates the water seepage beneath roadways can lead to potholes in roads.

SOLUTION

The SVFLUX software may effectively be used to model the climatic influences surrounding road design. The amount of flux that can be expected to infiltrate beneath a road can be calculated. The coupled SVFLUX and SVHEAT software allows the location of the interface between ice and water to be calculated.

Please note that most of these models can be downloaded through our SVOffice product suite.
