Recommandations for the use of noise reduced pavements in urban areas
Tests for noise reduced pavements in urban areas and controlling, technical and physical development of the pavements
10 types of surface and their recipes were set to be examined. To improve the acoustic long-term behavior were partially materials such as EOS, Famsa or Gasperini chosen. In addition rubber granules were mixed to individual surfaces.
The selected surface types were shared with the cantons. Cantons should installed the surface on suitable test tracks. All test sections are tested on existing roads, provided with new surfaces due to construction and / or noise reasons.
In addition to this were 9 other a few years ago built coverings in the research program comprised, that were considered low noise.
Testing of new road surfaces on real roads.
Improving the characterisic of road surface and decreasing of noise.
