Until now, we haven't had a confident decision making system for priority of the pavement maintenance though the procedure of PMS is about 15% of total road maintenance procedure. So, the budget for road maintenance have inefficiently allocated to road maintenance projects regardless of priority without scientific analysis or reasonal decision making system.
Also, we couldn't well consider qualitative indexes even though these kinds of factors affect on the feasibility of road maintenance projects.
In this study, we suggested a level structure and criteria that can be adopted for the appraisal of urban road maintenance projects. Also, the results of characteristics of preference indicates that present situation of pavement road is considered as the most important factor getting weighted value of 0.452 as we expected. But the affection factors to destruction and policy factors are also considered as a important factors. It means that we need to establish a model to support priority appraisal. Also, there are no statistical difference of weighted value among factors by specialists.
