Abstract

The surface characteristics of asphalt pavements are currently measured indirectly by multiple parameters and"br" characteristics, such as skid resistance, evenness and brightness. Safety is one of the main criteria, when"br" designing asphalt pavements and is represented by the performance measure friction. To improve the friction"br" most asphalt surfaces are gritted with a chipping material directly after the paving process. One of the main, still"br" unsolved problems is an insufficient embedding of the chipping material into the surface to avoid significant"br" material loss. With an early integration of chipping material during the paving process, a better bond between the"br" chippings and the asphalt could be achieved."br" This paper shall give an overview to the various interactions between surface texture and surface properties, as"br" well as specific recommendations to produce high skid resistance and durable asphalt surfaces.
