Les effets de la texture et de l'uni des revêtements routiers sur la consommation de carburant.

In order to estimate the effects of road surface evenness and macrotexture on vehicle fuel consumption, three practical experiments were carried out: 1) in the laboratory on a vibration bench to simulate unevenness, 2) on a test track to reproduce extreme macrotexture values, and 3) on normal roads. The usual testing methods were used to characterize the carriageways.
