Australian Road Lifespan Threatened By Bitumen Oxidation
Australia faces a potential shortage of bitumen or asphalt supplies within 30 days due to supply chain constraints. Chief Executive Michael Caltebiano warned that high sun intensity causes bitumen to oxidize rapidly under local conditions. This oxidation is expected to strip years off the lifespan of Australian roads. The industry will require refreshment and rejuvenation efforts within six to eight years to maintain infrastructure.
