I'm trying to create a design control template for the following conditions and I need some advice. We are improving an intersection by milling 2" and repaving the surface, plus widening and putting in a right turn lane with a taper on the right side. So with a 2% grade on each side of the road, I need to have the right side of the template with curb and a base course that widens with the right alingment beginning 2 feet from the edge of the existing edge of road where ther will be a saw cut. Should I include the curb with the template or as a subassembly. And how can I get the base assembly to start from 2 fett of edge of road?
