This article summarizes the results of real tests carried out on roads, with light and heavy vehicles, aimed at evaluating how much more fuel is consumed when driving on a road in poor condition, as well as the associated emissions generated. In the case of light vehicles, differences in average fuel consumption were 3,5% lower in newly paved roads, while in the case of heavy vehicles, the reduction reached 4%. The research assessed the effect of improving surface condition of the Spanish rural network, from a conservative hypothesis, saving almost 600 million liters of fuel and 1,5 million tons of CO2 per year. The research was developed with the support of the following organisations: Becsa, Eiffage Infraestructuras, Mercedes, Ponle Freno and Probisa.
