The paper deals with the assessment of wear of road surfaces subjected to traffic. Full-scale tests were performed by means of LCPC Carousel facilities to simulate passages of truck tires under pure cornering maneuver. Three types of road surface were tested. Up to 800 000 passages were performed and measurements of tire and road characteristics were carried out at different wear stages. Results were presented in term of evolution of skid resistance as well as macro- and microtexture of road surfaces. Tire wear was simply assessed by tire groove depth evolution. Discussion was focused on the relationship between evolutions of road surface microtexture and tire groove depths to assess road aggressiveness vis-à-vis tire wear. The study is part of European TROWS project that the main objective is to derive experimental and numerical tools to predict tire and road wear.
