Abstract
The paper presents a study aiming at understanding the wear of a dense asphalt concrete, especially the behavior of its bitumen layer. Tests are conducted in laboratory to simulate mechanical actions induced by traffic. Friction and texture analyses are completed by microscopic observations to identify involved processes. Studying the variation of wear volume with energy dissipated by friction helps to estimate wear rates. Explanations are provided in terms of damage mechanisms occurred in the bitumen layer.
