Abstract: Asset management is the main stream for road structures, yet the management system to determine service standard and maintenance/repair level is not established. For example of road pavement these are set by traffic volume, by road grade, or just by the road condition. This study is to establish methodology to determine appropriate service level and budget allocation for infrastructure management, in this case for road pavement, with a new evaluation system of infrastructure value by applying depreciation model which can evaluate correctly asset conditions corresponding to maintenance/repair pattern. Management system also assures accountability of budget allocation by this numerical method. Service standard and maintenance/repair level was derived from equilibrium point at the service market of driver’s demand function (satisfaction function) and service providing cost function. Driver’s demand function was set up as an outcome (=satisfaction level to road condition) index. Service providing cost function was derived by evaluating the optimized maintenance/repair pattern based on the lowest life cycle cost for the required asset value necessary to provide certain service level. If we treat roads as service markets, this equilibrium analysis is able to determine the service level and budget allocation in various roads in accordance to the equilibrium point of satisfaction level and service level. It is also possible to determine the satisfaction level of drivers among roads under budget restriction by conditional equilibrium analysis, such as setting equal satisfaction standard for every road.
