This report deals with a concept applying residual value estimations to applications in optimisation and procurement of road construction and maintenance. The purpose is to develop a framework and concept for tieing together technical and economical considerations in order to contribute to more optimised construction and maintenance of roads in a long-term perspective. This report is limited to investments in the pavement. Initially, the term residual value and its application in this context is investigated. Then, possibilities for prediction of pavement deterioration and performance are presented. These models are also linked to prediction of maintenance needs. Finally, a concept for cost predictions is developed with corresponding residual value applications, for example performance procurement, payment models, as well as more optimised pavement management from a life cycle perspective.
