Road traffic noise is becoming a matter of concern, particularly in the urban environment. The aim of this study was to evaluate the noise generating properties of different asphalt road surfacing types. Road surfacing type has a minor effect on the noise level inside vehicles at the higher speeds tested, but is more important at lower speeds. However, the surfacing type greatly determines the noise level measured alongside the road at low as well as high vehicle speeds. More noise is generated when the surface texture of surfacings that exhibit random asperities is increased.
