Key Messages 
Road infrastructure is exposed to different climate impacts, e.g. heat, high precipitation and flooding. Extreme heat but also a greater temperature variability will put a larger strain on road pavements, leading to cracks, rot occurence or pavement blow-ups. These pose additional risks to transport users. New constructin materials can be used to cope with these effects and to make pavement more heat resistant (e.g. new, heat-resistant paving materials, more common use of polymer-modified bitumen, improvement in pavement technology, using polymeric grids to avoid rutting, using materials on the surface which reflect solar radiation). Damages from flash floods and extreme precipitation events can be avoided through proper and scheduled maintenance of drainage. In some regions, where intensive precipitations are likely to increase, an upgrading of drainage should be considered.
