Advantage 34

Recent research in the Netherlands showed the potential of asphalt pavements to reduce rolling resistance and depending on that reducing fuel consumption.

Research of the Dutch Ministry of Infrastructure and the Environment showed a clear dependency of the rolling resistance to the texture of the asphalt road surface respectively the grading of different asphalt mixture types. It is possible to decrease the rolling resistance for passenger cars by approximately 10%, by varying the road surface grain structure from rough (0/16) to fine (0/6). With this figure of 10% and an influence factor of 20-30% for the rolling resistance on the fuel consumption it is estimated that fuel consumption and CO2-emissions can be influenced with 2-3%.
