Résumé / Abstract
Based on results from the former project “Prediction and Propagation of Rolling Noise” developed in the framework of the German-French cooperation and during which an optimal low noise texture of dense road surface has been designed, ODSurf, financed by the French Environmental Agency and the German Federal Highway Research Institute is mainly devoted to the implementation of new technologies and materials particularly adapted for urban situations in terms of noise abatement to comply the European noise regulation. Different new solutions have been investigated. To achieve our objectives, we improved and/or developed new predicting models and experimental techniques. A particular attention has been paid on the consequences of texture, horn effect and air pumping modifications on tire-road noise emission. Theoretical approaches and new optimized road pavement designing have been carried out in parallel. Furthermore, the improvement of “conventional” wearing courses has been pursued in order to supply to end-users a complete set of low-noise solutions adapted to their own situations. First validation results are presented. Further, these new optimized pavements will be introduced in the common DEUFRABASE, previously implemented for suburban configurations, which will be completed and extended to urban situations.
