Abstract

The management of urban road pavements is a complex activity which is particularly severe from the economical point of view. In order to optimise the maintenance operations, it is necessary that all the operative phases are co-ordinated within a unique planning system, and therefore the data collected on the pavements conditions are to be used as input for the analysis and the decisions, in order to assess “where”, “when” and “how” to intervene. The paper, starting from the real case of the planning of the maintenance of the urban roads network of the city of Potenza, shows the phases of parameters collection on the fails of the pavements, of data implementing and of interventions planning, defining at the same time a methodology which could be an aid for the planning of the maintenance of the urban roads. The Author proposes the use of the G.E.I. (Global Efficiency Index) of the pavement as an instrument to monitor the evolution with time of the efficiency of the structural pavements from the point of view of global performances. The definition of the G.E.I. function, by means of the assessment of few indicators (e.g. superficial degradation and/or adherence), allows to follow the decay of the pavement itself with time, the G.E.I. decay curve concept being as a consequence defined. This instrument can be placed at disposal of the Administrations of infrastructures and allow to plan the road maintenance for a long period.
