SIlent Road for Urban and Extra-Urban Use [SI.R.U.US]: the innovative resilient and resonant pavements

The idea of a new kind of pavement with a low acoustical impact on the environment grew out of the need to control rolling noise and other noise sources, not just at high frequencies, but also at low and medium frequencies; i.e those frequencies found in particular traffic and driving conditions on motorway and urban roads, such as heavy vehicle traffic and cross-roads with traffic-lights. This has been the noise control/abatement approach of the European multi-partner SI.R.U.US. project (acronym for SIlent Road for Urban and extra urban USe) which have referred not only to reduced tyre/road noise emissions relating to the top layer, including the absorption of vibrations through a "resilient or dumping" behaviour, but also to tyre/road noise and engine noise absorption obtained from the "resonant" behaviour of the surface course and deep layers. This approach led to the definition, design and implement of alternative solutions for innovative silent pavements that addressed other factors besides the surfaces. This paper reports on innovative low noise road surface and pavement solutions from surface measurements results by laboratory and on site tests to structural characterisation and design. The conclusions includes also a critical overview and a discussion of the needs for further research and the development of industrial production techniques for finished innovative silent pavements.
