Microclimatic and environmental actions of road structures

Various areas of a highway structure are studied regarding their level of exposure to the surrounding microclimate. Climate conditions from meteorological stations and vehicle kinetics are used to determine zones that are exposed to salt products and climate. Dividing a highway into structural elements based on exposure takes into account the significant spatial variation and helps define zones of equivalent sensitivity to deteriorations. Based on Swiss meteorological stations, highway structure monitoring, inquiries with public authorities, in situ spot measuring and literature surveys, this article precisely highlights the microclimate of these structures. This approach can help define the various exposure areas of the structures, namely salt mist, splash and water stagnation areas as well as determine the significance of the microclimate in order to predict the evolution of structural deteriorations.
