This report comprises a technical review and update on new knowledge about salinity impacts and pavements. A review of recent literature and research outputs has indicated that there are knowledge gaps in the area of how salinity affects pavements and these are discussed in the report. Climate assessment and watertable trends throughout Australia are also discussed. There has been a decade of drier than average years throughout many parts of south-eastern Australia and south-west Western Australia, resulting in a prolonged soil moisture deficit. A reduction in winter spring rainfall has meant a lowering of the watertable in many salt-affected catchments.
