The paper gives an overview of three recent research projects carried out at LCPC (Central Laboratory for Roads and Bridges, Nantes, France), dealing with concrete pavement. In the first one, a laboratory fatigue test was developed in order to measure the toughness of interface in composite pavement structures, having a Portland cement concrete base course cast over an asphalt subbase course. In the second project, a new structure was developed where a thin, unbonded and reinforced wearing course in high-performance concrete was supported by a hydraulic, cracked base course. The third project dealt with the recycling of reclaimed asphalt pavement in cement concrete; a new, hybrid material was examined, and showed interesting properties for pavement applications. It was concluded that a part of the future of PC concrete in pavement lies in the association with asphalt materials.
