A Review: Pavement Surface Micro-texture and Its Contribution to Surface Friction
Understanding the contribution of surface texture on tire-pavement friction remains a major challenge in order to provide good mechanical modeling of the grip and rolling resistance performance of tires. It has been more than fifty years since early studies on the micro-texture and still no general agreement has been found either on its characterization or on its role in friction. Therefore, the authors reviewed the literature dedicated to this subject over the past two decades. The authors present the experimental evidences, which prove that current surface characterization parameters are insufficient for drawing a seamless correlation to friction. Surfaces represented by similar micro-texture parameters show different friction behavior. Then, the models dedicated to fit the correlation between friction and surface micro-texture are studied. To overcome the limit of oversimplified surface representations, several contact models have focused on representing friction with respect to the more complex representation of the surface. Various theories have been proposed, but none of them has been supported unanimously. Nonetheless, these theories favor the emergence of physically based coupled tire-pavement models.
