Typical values have been estimated per km road regarding the use of energy and carbon dioxide emissions for construction as well as maintenance and operation for four separate cases. These cases have been defined from standard motorways, 2+1-roads (Swedish standard road with alternating one and two lanes in each direction) and normal two lane roads. The two lane road was further divided mainly with respect to traffic flow into two separate cases. These four cases have then been analysed during the phases of construction and service for 60 years. The resource needs have been quantified in terms of material and activities. In the next step, the resources used have been translated into energy and carbon dioxide emissions. Furthermore, a typical tunnel and motorway junction have been added to the list of cases analysed in the same manner.
