NOISE FROM RETEXTURED NEW CONCRETE AND ASPHALT ROAD SURFACES

Road surface texture is well known to influence both vehicle noise and skid resistance. Since there is a tendency for a surface with high skid resistance to be a "rough" one, and for a rough surface to be noisy, the pavement designer and the acoustician have traditionally been thought to have opposing roles in pavement design. But the scientific basis for progress towards the two seemingly incompatible goals of high skid resistance and low noise is that the textural characteristics that affect them are not the same. Skid resistance is associated with road surface textures that do not give monotonically-increasing amounts of noise. W. R. Fuller found evidence that noise is quite high with very low values of many "roughness" parameters, drops as they increase, then rises again. The paper discusses these factors, and describes a relatively high "roughness" asphalt pavement developed in Ontario that is not only much more skid resistant than worn concrete, but is also much quieter. Furthermore, certain retexturing treatments for worn concrete pavements are shown to have widely differing noise characteristics despite their essentially similar skid resistances.
