Follow-up of the pavement level of service on a French toll motorway

Autoroutes du Sud de la France (ASF) is a private firm, which exploits the longest toll motorway network in France (2500 km). With such a large network, ASF set up a pavement management system. This system is essential to well know and to follow-up the level of service offered to customers, and to anticipate the budget needs. The management system is built on the intern monitoring policy, which defines the condition survey to do and its periodicity. Condition survey affects more particularly the following characteristics: roughness and skid resistance, rutting, evenness, distresses. The results of condition survey are entered into a data base, which also contains essential data for a good pavement knowledge, as the nature of the different courses, their thickness and building dates. For each characteristic, we then have a lot of measures each year. The measure value is compared to thresholds, in order to obtain a level of service: from A for a good level, to E for a bad level. We obtain in this way the repartition of level of service on the motorway network for each characteristic. To have a global image of the network, indexes are created by crossing characteristics. We can then obtain an index representative of security, or comfort or also a global index which uses all the characteristics. For each index, we then calculate a mark. The comparison of motorways between them or the evolution in time is done with the marks analysis. The article will present in detail the index and marks calculation methodology, the management system and the results analysis to follow-up the level of service (A).
