In a context in which many projects have been executed in public-private partnership (PPP) mode in recent years, it makes sense to explore the various pavement performance criteria used by agencies for recent road projects developed in Canada. After describing the various types of criteria used for pavements, such as ride quality, rutting, surface distress, skid resistance, structural capacity and frost susceptibility, their individual target values are reviewed. Adaptations of the performance criteria to enhance the effectiveness of the specifications for each of the parties concerned are suggested. Finally, the impact of the criteria and target values on the intervention cycles is analyzed in terms of technical constraints and life cycle maintenance cost aspects.
