Climate change impact on the pavement maintenance and rehabilitation costs associated with the Australian national highway network.
The study compared pavement maintenance and rehabilitation costs for a year 2100 climate projection (based on a high emissions scenario) and "climate-adjusted" population projections, with present day levels, and determined the following major outcomes: 1. Nationally, there is a small decrease (between 0 and 3 per cent) in the required pavement maintenance and rehabilitation budget based solely on climate change factors. This result reflects the generally warmer and drier Australian climate (i.e. reduced precipitation lowers the rate of pavement deterioration). 2. Annual pavement maintenance and rehabilitation budget is estimated to increase by around 30 per cent (considering both the influences of climate change and transport demand changes). 3. There are significant regional variations in the change of pavement maintenance and rehabilitation costs as a result of climate variation and population and transport demand trends. For example, increases of over 100 per cent and 50 per cent are projected for the Northern Territory and Queensland respectively, due to the larger population increases and wetter climate expected within this territory and state.
