This paper gives an overview of the collaborative research project Alternative Materials in road construction. The project was part funded by the European Commission and was carried out by a consortium of nine organizations in seven countries. The objective was to develop test methods to assess the suitability of alternative materials in road construction, concentrating on unbound granular applications such as sub-base and capping. The project activities are described and a toolkit of test methods for mechanical, leaching and hydrodynamic properties is presented. Case studies of the performance of alternative materials in roads show that they give as good performance as natural reference materials and have not caused pollution of groundwater. Mitigation measures are discussed and areas for further research identified
