Union overlapping polylines and summarizing attributes

I have a shapefile containing many overlapping polylines that represents different paving operations of road segments. Every polyline contains many attributes and one of the attributes is the increase [cm] of pavement thickness. The  goal is to unify these polylines and sum the total pavement thickness in every section of the road. What should I do?

I hope the photo clarifies the situation.

I would generate a 3D surface with the thickness data of each line as elevation, then apply map algebra to sum that value in every surface and finally use "Interpolate Shape" tool to get the accummulated thickness. If there's another way to do it I would like to know it
