Low-noise road surfaces are recognized as a cost-effective tool for traffic noise abatement. The best performance can be achieved by optimizing surface texture and porosity. That way, a bottom line of a 3dB lifetime average reduction with respect to ordinary asphalt has been reached. Any progress must resort to another noise-relevant characteristic i.e. elasticity by which the noise due to tyre v ...

"The contribution that the road surface makes to road safety is often underestimated. Whilst first advances have already been made in the technology of tyres and braking systems, at the time of an accident or near-accident one of the major underlying factors is the condition of the road. The awareness of such issues varies widely across the EU. In the United Kingdom, which has one of the best road ...
