Résumé

To achieve sustainable road networks, long-term social and environmental costs and benefits related to traffic emissions should be recognised and incorporated in the decision-making process of pavement management units. A new tool designed to monetize and incorporate social and environmental impacts in decision making processes was used to assess the life cycle social and environmental benefits of pavement management related to traffic emissions. A case study regarding a 1 km long section of an urban collector road located in Montréal, Canada is presented in this paper. The case study shows that pavement surface maintenance provided an estimated social and environmental benefit ranging from $235 000 to $5 150 000 over a 40 year analysis period, depending on the maintenance treatment applied and the discount rate used. Despite uncertainties, the results unambiguously show that benefits related to traffic emissions were significant and were the same order of magnitude as the maintenance costs. As such, they deserve to be incorporated in the life cycle assessment of pavement maintenance strategies. Preventive maintenance was also found clearly more effective than corrective maintenance to mitigate exhaust emissions.
