Key Messages 
Airports are 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 airport runways, leading to cracks, rot occurence or pavement blow-ups. These pose additional risks to outgoing or incoming planes. New construction 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 of airport runways. In some regions, where intensive precipitations are likely to increase, an upgrading of drainage for airport runways should be considered.
