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. |
