An innovative material, called Grooved Fibre-Reinforced Ultra-High Performance Concrete (GFRUHPC) is presented in this paper. In the framework of an international OECD project, supported by a French ANR project, the aim was to develop an hydraulic material for long-lasting wearing courses, devoted to highly trafficked road sections. The current solution is a fibre-reinforced UHPC, longitudinally textured for the sake of surface drainability. Titanium dioxide can be also incorporated in order to provide an additional air-depolluting capacity. An experimental construction site was carried out in 2011 in Loire-Atlantique (western France). Measured performance in terms of skid resistance, noise generation and depolluting capacity are encouraging. Necessary technological improvements are given in conclusion, for the sake of industrial maturity and dissemination of a globally sustainable material.
