ADHERA
Device measuring a CFL using a locked wheel fitted with a smooth tire.
Adhérence ; Skid resistance
Contribution of the pavement surface to tire/pavement friction. This is a friction coefficient measured under specific, or even standardized, conditions in terms of test tire, loads applied, speed, etc.
Membership; Adhesion
Friction forces generated by the dissipation of energy linked to the stretch-break cycles of the molecular bonds between the tire and the road surface.
Coefficient de frottement longitudinal (CFL); Longitudinal friction coefficient (LFC)
Ratio between the horizontal friction force F (generated by a braking wheel) and the reaction R normal to the ground due to the load on the wheel.
