This project aimed at the optimisation of new road pavement concepts with respect to tyler road noise in a wider context of the abatement of road traffic noise. French and German institutes headed by the 'Laboratoire Central des Ponts et Chaussees' (LCPC) in Nantes and the 'Bundesanstalt für Straßenwesen' (BASt) in Bergisch Gladbach cooperated throughout this project, which finished in March 2009. It was funded in the framework of the French-German-cooperation 'DEUFRAKO on the French part by the PREDIT III Programme and on the German part by the Federal Ministry of Economics and Technology. The theoretical approach is based on the SPERoN ('Statistical Physical Explanation of Rolling Noise') model developed by one of the partners and already implemented and tested in Germany on a large set of measurements carried out at the experimental site in Sperenberg near Berlin. In the first stage of the project, the model was validated for different kinds of French road surfaces. In a second step, the model was applied as an adapted tool to design and build new textures for low noise road surfaces. Finally, in a third step, the results issued from SPERoN were used as an input for outdoor sound propagation models developed in France and Germany in order to estimate the effect of this optimised model-aided low noise pavement in the far field, close to the facades. A ranking with other typical German and French pavements lead to a common database (DEUFRABASE).
