Abstract: In the beginning of the 1990's FinnRA suggested decreasing resources for the Lapland highway district whereas the district felt that such a policy would have very harmful long term effects. To fully comprehend the implications of the proposed budget cuts, the district initiated a study on the impacts of different strategy alternatives on the road network condition, agency and user costs, maintenance level of service and on the regional economy. In this study, a network level pavement management system was used to allocate and optimize funds for rehabilitation. Summer and winter maintenance was analyzed with analytical hierarchical process and as to investments in addition to traditional cost benefit analysis, regional multiplier effects were studied with a regionalized input output model. It is evident that rehabilitation, summer and winter maintenance, and highway investments cannot be viewed independently of each other. Road keeping has to be seen as a whole and the optimization of its sub-components has to be done simultaneously. Mathematically speaking this means that pavement maintenance, summer and winter maintenance, and highway investments are non-separable from each other and that the optimization function has to cover them all.
