This paper presents a procedure for ranking environmentally valid highway restoration by priority, using a Fuzzy Multi-Criteria Model that supports decisions on which road segments require these works and services. This is a matter of much concern for the Brazilian Government, due to rising awareness of soil degradation and the depletion of plant cover, as accident rates and transport costs rise steadily. The criteria used are: risk of accidents, economic and strategic importance, environmental degradation and the risk of erosion and landslides along the highway. In order to apply the proposed model, an example compares two highway segments, conducting sensitivity analyses through weighting the sub-criteria and criteria.
