A number of public road laboratories are working together in an OECD/ECMT project. The aim of this project is to evaluate two technical solutions for long-life wearing courses. It is intended that these would eliminate maintenance works for several decades after construction. One of which, called HPCM (High-Performance Cementitious Material) consists of applying a thin layer of fibrereinforced ultra- high-performance mortar, in which calcined bauxite chippings are inserted. After a presentation of the mixture-design and the laboratory application technique, the results of tests dealing with stripping, fatigue, shrinkage-induced cracking and resistance to freeze-and-thaw are given. In conclusion, the rest of the program is listed, which should allow the participants to organise real trafficked test sections in a further phase of the project.
