I am creating a 3D model for an urban, multi-lane widening project for FDOT. At the beginning and end of the project there is no profile grade required, since I am connecting to the existing pavement by milling (stripping) and resurfacing (overlay). From Begin to End new pavement construction there is a proposed profile grade. It seems that there could be at least two methods to create the model.
Please provide comments and insight on the best approach to model this scenario.
I would propose using the existing ground profile as your active profile. For your new pavement template, add an additional center line point (set as the template origin) to follow the existing and use a vertical point control to move the new pavement center line to follow your proposed profile.
