Beschreibung
Zusammenfassung:	A road surfacing for reducing rolling noise includes particles bonded together so as to form between them air-permeable channels. The material of the road surfacing includes a ballast material comprising granules of stone and rubber and a bitumen binder adhering to the granules of stone and rubber. The granules of stone have particle sizes ranging from 0.5 to 24 mm and the granules of rubber have particle sizes ranging from 0.5 to 8 mm. A method of manufacturing the material as well as a method of laying a road surfacing are also described. L'invention concerne un revêtement de routes permettant de réduire les bruits de roulement et comportant des particules liées de manière former des canaux perméables à l'air. Le matériau de revêtement de route comprend un matériau ballast contenant des granulés de pierre et caoutchouc et un liant bitume qui adhère aux granulés de pierre et caoutchouc. Les granulés de pierre ont des tailles de particules comprises entre 0,5 et 24 mm et les granulés de caoutchouc ont des tailles de particules comprises entre 0.5 et 8 mm. L'invention concerne également un procédé de production du matériau ainsi qu'un procédé d'application du revêtement de route.
