The purpose of the research was to determine the relationships between skid numbers and small-scale textures combined with macrotexture parameters. The results of this research stress the importance to driver safety of the microtextures and the small-scale macrotextures of aggregate particles exposed on pavement surfaces. These textures together with the macrotextures as measured by the Profilograph and the distribution of the aggregate size have a decided influence on the skid number measured by a locked-wheel trailer and hence on driver control. The results also show that low values of macrotextures are indicative of poor drainage from the tire-pavement interface. Low values of void areas result in large reductions in skid numbers as the skidding speed increases. (Author)
