I don't believe a level on the BB will help. First, you don't want the road to be level. It won't shed water and develop potholes. When grading the road, you want to put a crown in the middle. You can do this by setting you blade a bit high on the left, while you work on the right. Then on the return trip, again working the right, the left side of the BB will leave a crown.
If you have long stretches of slope, you want to put diagonal swales to carry off some of the water every so often. Volumes of running water works against you. You must divert and spread the water from your road.
A level will tell me what parts of the road are currently level, or sloped to one side or the other.
The road is sometimes bermed at an angle and the ditch that I create will be on one side only. I won't be creating a crown on every surface of every road. I've utilized some diagonal swales. I haven't made any that completely cross the road though. That seems like it would be hard to maintain. I'll have to research that concept more. I have numerous areas where a flow already crosses the road in a natural diagonal. They get deeper quick.
