3. Grip evolution

Pavement skid resistance changes over time under the influence of traffic and climate. Knowing this evolution in advance makes it possible to :

  • monitor the condition of infrastructure (roads, tracks) and plan maintenance;

  • guarantee performance and optimize the use of materials.

The evolution of a pavement's skid resistance is linked to three main mechanisms:

  • wear caused by friction between the tire and the road surface. Polishing is a consequence of this wear;

  • ageing of the material due to climatic conditions (temperature variations, action of oxygen in the air, acid rain, etc.);

  • seasonal variations: grip generally reaches its lowest value in late summer and...
