Abstract
The world seems to be increasingly effected by extreme weather events. Whether these are attributable to climate change is debatable, extreme weather events seem to be more frequent. This paper considers how the effect of extreme weather on the performance of surface course asphalt can be predicted through laboratory study. Weather related factors such as temperature and rainfall are compared with asphalt related factors such as mix type, aggregate, bitumen, compaction and trafficking. Examples are given of laboratory studies that consider how the inter-relationships between factors can be assessed. For example, how surface drainage or the detrimental effect of surface water entrapment can be quantified in the lab with physical tests and 3D modelling.
