Résumé / Abstract
From a ranking of road pavements established in the near field of the road according to ISO 11819-1 standard, it becomes possible to predict the road traffic noise in the far field taking into account the acoustical characteristics of the road surface. Theoretical results obtained from a predicting model including ground and atmospherical effects are advantageously compared to in situ measurements carried out in the neighbourhood of roads covered with various types of surfacings.
