State of the art of likely effect of climate on current roads

The future climate change and its influence on the performance of the road network is an issue that is concerning more and more countries. It will be shown in this report that the predicted changes will affect highways performance, most likely in a negative way. If temperatures rise and precipitation increases, it looks as though present design theory and construction techniques must be amended to accommodate for these differences of climates. Some governments and organisations have already started facing the problem by financing studies and projects with the aim of finding possible ways to precaution.
