Abstract: The concept of sustainable development calls for a change of the way about how projects should be appropriate managed. Generally speaking, maintenance management, as an integral part of the whole life cycle asset management, are well developed based on cost effectiveness and performance improvement. Due to the rising recognition of environmental and social concerns, there is a need to include sustainability into the maintenance management of road projects. This paper will innovatively evaluate the environmental impact of road pavement maintenance strategies in Australia through life cycle assessment. Eight pavement maintenance strategies, from asphalt replacement to slurry seal, are investigated. The results show that 2.15 to 9.92 kg CO2 e/m2 can be generated by maintenance strategies at the project level. Maintenance stage has relatively low impact on carbon emissions when compared to the construction stage. However, at the network level, the annual monetary value of the carbon emi ssions from maintenance strategies is estimated to be A$3.27 million, which is significant when compared to the maintenance budget. The results offer useful insights for road authorities to report their performance on sustainability and make relevant maintenance decisions. (More)
