lubrifiant

OBS: Lubrifiant. Automobile. Substance liquide ou solide interposée entre deux pièces en mouvement relatif pour faciliter le glissement et réduire le frottement.

CONT: [Functions of geotextiles]. Lubricator: the geotextile is placed between two materials which have to move along each other; its function is to reduce interlocking (adhesion and friction) between these two materials. An example is a multilayer concrete-geotextile-geomembrane pavement for a canal lining where differential movements are expected.
