The efficiency of the road management system is increasingly challenged due to the frequent occurrences of extreme weather events, such as intense heavy rainfall, cyclones and flooding. The unpredictable events such as Hurricanes Katrina and Rita in the USA (2005), extreme flooding in January 2011 in South-East Queensland, Cyclones Oswald (2013) and Marcia (2015) in Queensland had severe impacts upon the road infrastructure. These roads are now subject to a wider range of climatic conditions over their service life than was originally anticipated during their design. To date, no deterioration model can accurately predict the impact of floods on pavements. To understand the impact of January 2011 flood on the structural performance of flood affected pavements, Falling Weight Deflectometer (FWD) deflection data and surface condition data (rutting and roughness), on flood-affected roads managed by Brisbane City Council, Department of Transport and Main Roads (TMR), Queensland and Roads and Maritime Services, New South Wales (RMS, NSW), Australia, were collected and examined.
