Second pan African conference on road maintenance and rehabilitation

Abstract

An economic criterion of profitability can only be determined in the context of an overall policy of management of the road system. The analysis is a comparative approach which requires that a policy of road management has been previously established on the basis of a transportation plan, or which amounts to much the same thing - on the basis of a master plan leading to the establishment of a programme of work covering a number of years. It is never a question of deciding whether a given pavement should be maintained or not, but rather of selecting from among all the itineraries of the road system those which have to be maintained and those which have to be overlaid, and of working out the corresponding budgetary allocation and consequently, in the light of the annual maintenance and overlaying budgets, selecting priorities. From the technical point of view, which is the one we adopt here, the feasibility study corresponds to the evaluation of the quality of the road system.
