ABSTRACT
Rehabilitation (restoration) of cement concrete pavements raises a number of problems for road engineers because of the rigidity of the structure. Solutions used generally fall into two categories: one which implies milling the concrete tiles (recycling them) and another solution which involves covering the existing pavement with asphalt road systems that behave well under traffic. This article aims to provide a multi-criteria analysis method regarding the choice of intervention in such sectors. The analysis will take into account three elements: - the cost - the degree of pollution of the technology that will be used - the duration of execution Each criterion will be graded according to an established algorithm and a ranking of the possible solutions will be made, based on this score.
