Objectives:

To examine the road surface contribution to tyre-road skid resistance.

Methodology:

An attempt is made to approximate the road surface texture with fractals, in order to take into account its accurate geometry. A qualitative relationship between road surface texture, expressed through fractal concepts, and skid resistance is recognised.

Key Findings:

  • Inadequate microtexture, as a result of the presence of polishable material, drops skid resistance and enhances RTI risk.

  • Inadequate macrotexture, as a result of faulty construction practice or wear, drops skid resistance, especially in the medium to high speed range, thus enhancing RTI risk.

Themes:

Skid Resistance, Texture

Comments:

Greek-based research but included as relevant to UK.
