Road transport is the major contributor to environmental noise, affecting some 90% of the proportion of the EU population exposed to unacceptable noise levels. Rolling noise has been identified as one of the research areas to be addressed to help reduce noise levels in order to avoid harmful effects of noise exposure and preserve quiet areas. Therefore there is a demand for quiet, maintainable road surfaces. Thin silent pavements have been used as such in various countries. In the Netherlands, however, porous asphalt is the first choice as silent pavement. As the expectation on durability and therefore the cost effectiveness of thin layers is high research is started within the framework of the Dutch Noise Innovation Program (IPG). In 2006 test sections have been laid all over the Netherlands with a total length of 35 km. An elaborated research program has been performed on noise reduction, safety and durability. First results are very promising and will be presented in this paper.
