Abstract: The corresponding synthetic optimization management of the facility in road and bridge management has become inevitable. An asset value evaluation method is proposed to link the value of the assets with the change of facilities’performance and then economic indicator is adopted to describe benefits of road and bridge maintenance uniformly. The synthetic optimization of road and bridge management，including optimum plan for maintenance，allocation of funds and optimization performance of road and bridge under the condition of fixed maintenance founds，is realized by the mathematic optimization method.
