This document reports on a EU-supported RTD project on COnstruction with Unbound Road Aggregates in Europe (COURAGE). The COURAGE Project is concerned with investigating the fundamental characteristics and mechanical behaviour of unbound granular materials that are used in pavement construction. In order to characterise the behaviour of granular materials, COURAGE draws on functional and simplified laboratory tests. This work is closely aligned to experimental field studies aimed at monitoring seasonal moisture variations and structural stiffness, through non-destructive testing. In addition, two full-scale pavement test sections were established and analysed to provide a link between the laboratory and field data. Work undertaken within the scope of COURAGE provides an improved practical means of assessment to enable the performance of such materials to be more rigorously defined. This in turn will assist in maximising the efficient use of unbound granular materials in road construction, improve consumption of currently wasted materials and provide increased reliability of pavement performance.
