From an engineering standpoint, road reconstruction is often considered the most difficult type of road design to perform. Rather than dealing with the pristine geometry of new construction, the designer is faced with integrating the design into the irregularities of existing conditions. Because of this, each cross section of the road can be an individual design requiring special attention to cross slopes, pavement irregularities, and many other potential conditions. Despite these challenges, the designer is still required to produce an accurate design and an accurate account of the required material types and quantities. After reading this white paper, you will have the technical foundation to perform various types of road rehabilitation and reconstruction design with the help of AutoCAD Civil or AutoCAD Civil 3D.
