✦ Synopsis

Pavement skid resistance has Iong been recognized as the most important parameter to reduce traffic accidents. The factors affecting skid resistance are numerous and very complicated. It is a difficult task to estimate the extent and direction of their overall contribution. This paper deals with the road surface contribution to tire-pavement skid resistance. Pavement surface is expressed through micro/macrotexture depth and density. An attempt is made to approximate this pavement surface texture with fractals, in order to take into account its accurate geometry. A qualitative relationship between pavement surface texture, expressed through fractal concepts, and skid resistance is recognized. This attempt yields encouraging results, although it is apparent that further research is required.
