The maintenance and the rehabilitation of the urban road pavements are not often based on systematic programand scheduling but rather on emergency or on other not identified reasons.Moreover the Life Cycle Cost Analysis (LCCA), the only peculiar procedure for the management pavement,finds its own application for highway and motorway, even if it is possible to search the best investment for theurban interstate and arterials.By the light of the quantity of the involved resources, it seems necessary to define an operative methodologyfor programming the maintenance and rehabilitation activities for the urban pavement. The paper is orientedtowards the development of a multidisciplinary approach to make decision on management of urban pavementusing the basic concepts of the LCCA and micro-simulation model to define a scheme of work zone thatminimizes the delay on the traffic flow.The best rehabilitation strategy should be characterized by the lowest users’ cost that depends on the timeperiod of the work zone, which is conditioned by both own scheme and the provided treatment, and on “socialcost” as increased travel time for queue generation .Different scenarios for different work zone plans were developed and a micro-simulation model was used toassess increased total travel time of a traffic flow within the maintenance area.In this work an analysis by means of the above mentioned approach was carried out on real scenario in the cityof Palermo in order to point out the several frames of the adopted methodology
