Preventive maintenance of roads
The preventive maintenance of the roads is a planned implementation strategy of low cost treatments aiming to efficiently and lastingly extend their lifespans. Delaying the implementation of a preventive maintenance policy risks to make it totally inefficient. The financing intended for the preventive maintenance must be available at the right time, since it aims to prevent and not to heal.
A lack of preventive maintenance inevitably leads to a much more onerous curative maintenance phase in order to repair the imperfections that have an important impact on the durability of the road.
The typical example of curative treatment is the resealing of potholes that are the direct consequence of untreated cracks in prevention.
In the establishment of the budget of the roads’ lifespan management, the thermal patching and the hot sealing of cracks appear as the best solution.
