road design

Hello,

 I am u new user of bentley powercivil v8i. I have created a DTM of a dune from survey data and i want to create a design of this dune with a road through it. this road has to lie under a defined slope and off course flat for a width of 8 meters. along the sides of the road, the terrain must lay under a slope of 45%. The total volume of the dune must be the same as before (the calculation of the volume is already done).

 

Can somebody give me a few hints to do this, how and which elements have to be created, how to adapt the slope of the road (in profiles?),...

 

Thank in advance!
