The Poroelastic Road Surface: Is a Durable Ultra Low Noise Pavement Within Reach? The Answer Provided by the EU Persuade Project

Affordable and effective traffic noise mitigation measures are highly wanted, e.g. for the “action plans” which are due for the European Noise Directive in the EU member states. Low noise pavements are an interesting option as they are a “source measure” and relatively cheap compared to other measures. A problem with the conventional low noise pavements is that the obtained noise reduction (typical 2 to 7 dB(A) is lower than what can be achieved with noise barriers (typical 7 up to 12 dB(A)). A poroelastic road surface (PERS), consisting of a significant amount of rubber and bound with an elastic polymer, such as polyurethane, has proven to be capable of reducing the tyre/road noise with 7 to 12 dB(A), i.e. as much as noise screens. A (very) limited durability and/or an insufficient skid resistance have been the major obstacles for its use. Since 2009 a consortium of twelve EU partners is working on the development of a useable type of PERS in the EU funded PERSUADE project. All relevant aspects (technical, environmental, economic, safety…) are being considered and solutions to all the remaining problems are sought in this project. Mixes have been developed which at least perform well in the laboratory and on small scale “pilot” test tracks on low traffic volume areas. In the course of 2014, full scale test tracks on trafficked roads have been built in Denmark, Belgium, Sweden, Poland and Slovenia. An extensive monitoring program has been started to extract as much information as possible from each of them. This paper reports about the development of the mix, the building of small pre-test and the full scale test tracks and the findings about the relevant parameters, such as noise reduction, skid resistance, rolling resistance and durability.
