Road construction consists of the draft planning, the manufacture and the maintenance of roads and pathways. It is a component part of traffic route construction and is therefore also to be assigned to the section of civil engineering. The task of road construction is the manufacture and maintenance of traffic routes for motor vehicles, cyclists and pedestrians. Since the natural ground cannot take this loading, the application of special road construction technologies is necessary. Road construction cooperates closely with the earthwork sector. Generally, the location of the ground must also be changed in case of road construction processes. In urban areas, path construction can also be included in the city planning.
