In order to increase knowledge of how fuel consumption corresponds to pavement type, the Swedish Road and Transport Research Institute was consulted to investigate the difference between an asphalt and a concrete pavement. Measurements were made north of Uppsala, Sweden, where a highway stretch includes both of the pavements. The study involved both light and heavy goods vehicles. In June 2008, results from a previous study showed a significant fuel consumption difference for light vehicles driven on bituminous and concrete road surfaces. Fuel consumption was 1.1per cent lower on the concrete surfacing (Jonsson och Hultqvist, 2008). The aim of the current study was to determine if this difference remained, in June 2010, after two more years of traffic and operation. The investigation was also expanded to determine any effect on heavy goods vehicle fuel consumption. If there is noticeable difference in vehicle fuel consumption on the two pavement types, the difference can be used during life cycle cost calculations and help determine the choice of pavement material.
