Influence de la rugosité géométrique d'un revêtement sur l'évacuation de l'eau a l'interface pneu-route et sur le dérapage des véhicules.

Statistics show an increase in accidents when driving on wet roads. Rainwater should therefore be removed as quickly as possible from road surfaces either by means of a marked geometric roughness or by cants. A drainometer which is an apparatus to study the behaviour of water in the tire-road interface is described.
