Superelevation

Hi

I need to create superelevation for my corridor. I have one arc with 75.5m radius. 

My corridor template has -25 0/00 side slopes, the right one has to go from -25 to +25 where I have the 75.5m radius.

Somehow I haven't succeeded to create one :-(. Is there anyone there who could guide me though.

I am using OpenRoads Designer 10.08.01.33
